Forward section of eyewall likely to be near or just west of Kenner LA within two-three hours and 20-30 miles east of Baton Rouge by 7 pm. That is based on 12z RGEM upper low positions verifying. This is not quite worst case scenario for New Orleans which would be in the first concentric band as of present configuration. MSY is closer to Kenner than most of the city however. It's a slight break for Baton Rouge if that track verifies as they would be on the weaker side of the eyewall or just outside it. However the heaviest rainfalls are likely to be in a zone 20-50 miles west of the track and those could amount to 12-15 inches given the slowing forward speed. River flooding will become a bigger part of the story by Monday.

Looks like Ida was taking a selfie.

Appears to be heading steadily towards the mouth of the Mississippi or within 25 miles west of that for landfall, and it reminds me of the 1900 Galveston hurricane which probably peaked around landfall at cat-4. I will take their word for the reduced surge threat where the levees are in place but what about water flooding up from the Gulf through low-lying areas west of the River? Has that been fortified at all? It has probably been quite a long time since this type of inundation occurred so close to greater New Orleans, cases that come to mind were further west.
-
Isn't the dynamic for Lake Pontchartrain rising water levels from a surge entering from the east? I don't think the northerly wind after Katrina was the real killer for the weakening barriers, it was the rising water levels. This track could bring surges inland through the swamps and up the Mississippi and also raise Lake Pontchartrain levels but that work done since 2005 might help. I think this will play out as worse for wind damage and in some parishes west of NOLA worse for flooding. It may be equal for wind damage along the MS coast, or not quite as bad. At this point I think evacuating west makes a lot more sense than east, as long as you go at least as far as east Texas.

On a regional basis this could be higher impact than Katrina, where all storm surge came in from the east and affected mostly areas southeast of New Orleans rather than west. This one is about 50 miles further west, and storm surge will come into regions on the west side of the Mississippi but could also repeat Katrina's surge into the southeast. Also it looks like it could be stronger in terms of wind gusts.

On track to pass this buoy just to the west in about 12 hours ... https://www.ndbc.noaa.gov/station_page.php?station=42003 Looking at all guidance, the thing that stands out is the lack of any disruptive influences, so that given the SST values ahead of the storm, intensification could be extreme. I think cat-4 is most likely but cat-5 is possible (around 28-29N). Also the track looks quite bad for surge issues not directly related to Lake Pontchartrain so that outcomes may need to be assessed independent of that sort of surge (although it could come into the mix and be partially mitigated by the aforementioned upgrades). Since no organized evacuation efforts seem likely, would hope that a very poor second best response is scrambled into place, which would be to position all possible military water rescue assets around Lake Charles through the day Saturday into Sunday morning, with the objective of moving them into affected regions Sunday night and Monday once a clear idea exists about where they are most needed. They are probably going to be needed urgently in parishes south and west of New Orleans if not in the city itself.

2021 North Atlantic hurricane forecast contest
Roger Smith replied to Roger Smith's topic in Tropical Headquarters
The table produced last week showing the counts you need now to reach your forecast targets has been updated on the assumption that Ida does make it to major (the first two numbers in this revised count are already verified). This table will be adjusted if Ida does not become a major, and also at any point that the count changes again (with two likely candidates out there this could be soon although I might wait for those to show their potential before doing the adjustments). (added later _ currently 10/4/2 with Julian, waiting to see what happens to TD 10 and these two both seem likely to remain only TS intensity, but will adjust the table after they are done with their work). (later _ Julian has already been declared post-tropical after a brief spell as a TS -- will now update the table for this known element). Some of our forecasts look very promising at this point with quite plausible "rest of season" counts to verify. -
August 2021 temperature forecast contest

Final scores for August 2021 Scores are based on the end of month values in the previous post above. BOS scores have been set by minimum progression (60, 55, 50 etc) as highest raw score was 56. However, some of the lower raw scores are maintained since they turned out higher than the progression values. The boosted scores have this symbol ^. 1% reductions for BKViking are incorporated into the scoring (*) FORECASTER __________DCA_NYC_BOS__east _ORD_ATL_IAH__cent_c/e _ DEN_PHX_SEA__west ___ TOTAL Roger Smith ____________100 _ 92 _60^__ 252__ 74_ 74 _ 96 __ 244 _ 496 _ 80 _ 74 _ 86 __ 240 ____ 736 wxallannj _______________ 94 _100 _ 55^__ 249 __ 68 _ 80 _ 60 __ 208 _ 457 _ 78 _ 74 _ 92 __244 ____ 701 wxdude64 ______________ 76 _ 84 _ 50^__ 210 __ 58 _ 88 _ 68 __ 214 _ 424 __ 72 _ 46 _ 98 __216 ____ 640 RJay ____________________ 90 _ 96 _ 30 __ 216 __ 34 _ 96 _ 84 __ 214 _ 430 _100_ 44 _ 62 __206 ____ 636 BKViking ____ (-1%) _____ 79*_ 87*_ 30 __196 __ 42 _ 91*_ 97*__230 _ 426 _ 79*_ 53*_ 71*__203 ____ 629 Scotty Lightning ________ 90 _ 92 _ 45^__ 227 __ 54 _ 74 _ 76 __ 204 _ 431 _ 70 _ 34 _ 92 __ 196 ____ 627 ___ Consensus __________ 80 _ 90 _ 32 __ 202 __ 44 _ 90 _ 82 __ 216 _ 418 _ 76 _ 54 _ 78 __ 208 ____ 626 RodneyS ________________62 _ 70 _ 35^__ 171 __ 68 _ 86 _ 70 __ 224 __ 395 _ 58 _ 80 _ 78 __ 216 ____ 611 Tom _____________________74 _ 82 _ 26 __ 182 __ 32 _ 86 _ 94 __ 212 _ 394 __ 80 _ 54 _ 80 __ 214____ 608 hudsonvalley21 _________ 80 _ 90 _ 24 __ 194 __ 20 _ 86 _ 80 __ 186 _ 380 _ 82 _ 50 _ 78 __ 210 ____ 590 ___ Normal ______________70 _ 72 _ 16 __ 158 __ 34 _ 96 _ 84 __ 214 _ 372 __ 50 _ 64 _ 98 __ 212 ____ 584 Deformation Zone ______ 70 _ 82 _ 45^__ 197 __ 44 _ 76 _ 44 __ 164 _ 361 __ 60 _ 86 _ 72 __ 216 ____ 577 so_whats_happening ___ 86 _ 92 _ 05^ __ 183 __ 06 _ 90 _ 92 __ 188 _ 371 _ 72 _ 58 _ 74 __ 204 ____ 575 DonSutherland1 _________78 _ 84 _ 26 __ 188 __ 34 _ 82 _ 64 __ 180 _ 368 __ 54 _ 46 _ 70 __ 170 ____ 538 __________________________________________________________ EXTREME FORECAST REPORT DCA _ At +1.5 Roger Smith with warmest forecast (+1.5) has a win.

The same is true for 2006 which had a total of 20.79" but only 12.24" of that in July-Aug. A third example is 2009 with a summer total of 21.38" thanks to 10.05" in June. 2007 had almost the same summer total as 2006 (20.62") but qualified for the above list in 15th adding 6.55" inches from June.

I would say probably yes it does exceed 10" by about Saturday 28th as weak fronts stall and waves move along them, but as to amounts, could be anywhere from 1-4 inches, so may only just make it. Toronto has weather records going back to 1840 and the early 1840s had some very heavy rainfalls there, which are probably before most U.S. stations began their observing periods, although Caswell's Providence RI journal operated from 1831 to 1860. There were no examples of two months both hitting 10" or more at Toronto but in years from 1841 to 1843 there was enough rain at Toronto to suggest to me that it might be quite likely some U.S. locations which may have been in the path of tropical remnants that were part of these events may have reached totals that high. Rainfall was particularly excessive in late July and early August of 1841, and September of 1843. I found five or six week intervals that measured over 12" of rain in both cases. Looking now at Caswell's journal the highest two month total I found was 14.75" in July-Aug 1853. However his journal indicates that a rainfall on the night of July 12-13 1834 overflowed the capacity of his seven inch rain gauge and he isn't sure how much actually fell that night. Although his journal is admirable for general completeness and attention to detail, there are a few missing days and possibly missing precip on a few occasions, also it was interesting that when a hurricane hit the region on Oct 7, 1849, he details the events but never mentions the word hurricane (this is listed as a cat2-3 landfall that caused over a hundred deaths in s.e. MA -- the track looks like it went just barely to the east of Providence since he never got into tropical air and winds went strong NE to NW). If you don't already have this bookmarked, the journal can be seen in its entirety here: https://books.google.ca/books?id=oYY_AAAAcAAJ&pg=PA168&source=gbs_toc_r&cad=3#v=onepage&q&f=false If that fails to load, look for the wikipedia entry for Alexis Caswell and then in the footnotes, the reference to his weather journal which was preserved by the Smithsonian Institute. Caswell is seen as one of the forerunners of development of late 19th century meteorological science in America.

I hadn't looked at it until this happened, it now becomes one of the heaviest 24h rainfalls not to be a daily record (there are a few higher examples). This may not be complete (top five that I found in the data base) but the following daily rainfalls are not daily records (the actual ones are also shown): LIST OF DAILY RAINFALLS >3.90" NOT DAILY RECORDS Rank __ Amt __ Date _______________ Record for date 01 ____ 5.60" __ Nov 8 1972 ________ 7.40" Nov 8 1977 02 ____ 4.26" __ Oct 8 2005 ________ 4.30" Oct 8 1903 03 ____ 4.19" __ Aug 21 1888 _______ 4.45" Aug 21 2021 04 ____ 4.05" _ Sep 21 1938 _______ 5.54" Sep 21 1966 05 ____ 3.90" _ Aug 9 1976 ________ 4.10" Aug 9 1942

As you know, NYC (Central Park) broke the daily rainfall record for Aug 21 with the heavy downpours late in the day (4.45"). The previous record of 4.19" from 1888 was also of tropical origins. H3 of 1888 made landfalls in south Florida and Louisiana, then tracked northeast with the center shown near NYC by 00z Aug 22nd, later near BOS. It may have retained TS intensity until about that time. The max and min listed for Aug 21 1888 were 72 and 63, suggesting perhaps east to northeast winds all day with those downpours probably lasting most of the day (a further 0.13" was recorded after midnight for the 22nd in 1888). The Aug 22 record for NYC is only 1.85" (1994), part of a total 3.02" rainfall on the 21st-22nd that year.

Have to wonder if the western closed low is pulling in the entire circulation of Henri, which will result in a NW or even WNW track for part of the night and landfall in western LI towards 15z. The heavy rainfall band looks like a boundary between circulations around the two upper lows. It would probably drift very slowly west if there is a capture, then the heavy rain bands of Henri would move into central LI. Eventually the remnant low could drift into the Hudson valley and move into southern Vermont and central NH.

2021 North Atlantic hurricane forecast contest
Roger Smith replied to Roger Smith's topic in Tropical Headquarters
The seasonal count has reached 8/3/1 with Grace briefly a major before (final) landfall and Henri now a minimal 'cane. (note Aug 27, Ida has reached hurricane status and most forecasts assume it will become a major, which would make the count 9/4/2 at that point. The table is edited as of today to reflect that status). (note Aug 29, Julian has come and gone as a tropical storm, table now edited again to reflect that, with the count 10/4/2). (note Aug 30, Kate has formed and seems unlikely to become a hurricane, so I have redone the table yet again for 11/4/2). (note Sep 2, Larry is already a hurricane and guidance seems bullish on its chances to become a major so with the count now 12/5/2 I have rejigged the table below for 12/5/3 (if Larry fails to become a major this will be adjusted later). (note Sep 8, Mindy has arrived in the Gulf of Mexico, expected to remain only a tropical storm ... count once again adjusted). (note Sep 12, Nicholas active in the Gulf, waiting to see if this one becomes a hurricane before editing the table). (note Sep 14, Nicholas did attain hurricane status near landfall, table now updated to reflect new count of 14/6/3). The seasonal predictions you made now require these future outcomes to verify: Required future tropical counts for seasonal predictions to verify _ This table will be updated as new data change the seasonal count _ _ Aug 27 table changed to reflect likely 9/4/2 count within 1-2 days. _ Aug 29 and 30 changes to 11/4/2. _ Sep 2 change to 12/5/3 _ Sep 8 change to 13/5/3 _ Sep 14 count is 14/6/3 FORECASTER _________________ named __ 'canes __ Major _____ additional named, H and M required Macintosh ______________________ 25 __ 14 __ 10 __________ 11 ___ 8 __ 7 Tezeta __________________________ 23 __ 14 ___ 7 ___________ 9 ___ 8 __ 4 Roger Smith _____________________23 __ 13 ___ 7 ___________ 9 ___ 9 __ 4 Southmdwatcher ________________22 __ 11 ___ 6 ___________ 8 ___ 5 __ 3 IntenseWind002 ________________ 22 ___ 9 ___ 4 ___________ 8 ___ 3 __ 1 hudsonvalley21 __________________21 __ 11 ___ 6 ____________7 ___ 5 __ 3 Newman ________________________ 21 __ 10 ___ 5 ___________ 7 ___ 4 __ 2 J_Keith_Lee _____________________ 21 ___ 9 ___ 4 ___________ 7 ___ 3 __ 1 Brian5671 _______________________ 20 __ 12 ___ 2 ___________ 6 ___ 6 __(-1) (6 6 0 best outcome) RJay ____________________________ 20 __ 10 ___ 5 ___________ 6 ___ 4 __ 0 WxWatcher007 __________________20 ___ 9 ___ 4 ___________ 6 ___ 3 __ 1 BKViking ________________________ 20 ___ 9 ___ 4 ___________ 6 ___ 3 __ 1 ___ consensus __________________19.2 _ 9.8 __ 4.7 __________ 5.2_3.8 _1.7 DonSutherland1 _________________ 19 __ 12 ___ 6 ____________ 5 ___ 6 __ 3 (6 6 3 best outcome) Ldub _____________________________ 19 __ 11 ___ 5 _____________5 ___ 5 __ 2 magpiemaniac ___________________ 19 __ 10 ___ 4 ____________ 5 ___ 4 __ 1 NCforecaster89 _________________ 19 ___ 9 ___ 4 _____________5 ___ 3 __ 1 Tom _____________________________ 19 ___ 9 ___ 3 _____________ 5 ___ 3 __ 0 Looking to the skies _____________ 19 ___ 8 ___ 7 _____________ 5 ___ 2 __ 4 (533 best possible) wxdude64 _______________________ 19 ___ 7 ___ 4 _____________ 5 ___ 1 __ 1 TexMexWx _______________________ 18 ___ 9 ___ 4 _____________ 4 ___ 3 __ 1 Cat Lady _________________________ 18 ___ 9 ___ 3 _____________ 4 ___ 3 __ 0 snowlover2 ______________________ 18 ___ 8 ___ 4 _____________ 4 ___ 2 __ 1 Iceresistance ____________________ 18 ___ 7 ___ 3 ______________ 4 ___ 1 __ 0 Rhino16 __________________________ 17 __ 10 ___ 4 _____________ 3 ___ 4 __ 1 (441 best possible) cptcatz ___________________________17 ___ 9 ___ 4 _____________ 3 ___ 3 __ 1 NorthHillsWx ____________________ 17 ___ 9 ___ 3 ______________ 3 ___ 3 __ 0 ____ "Expert consensus" _________ 17 ___ 8 ___ 4 _____________ 3 ___ 2 __ 1 TARCweather ____________________ 17 ___ 8 ___ 3 _____________ 3 ___ 2 __ 0 ____ NOAA median _____________ 16.5 ___ 8 ___ 4 ____________ 2.5 __ 2 __ 1 Yoda _____________________________ 16 ___ 9 ___ 5 _____________ 2 ___ 3 __ 2 (best outcome 3 3 2) LoboLeader1 _____________________ 15 ___ 9 ___ 4 _____________ 1 ___ 3 __ 1 (3 3 1 best outcome) Prospero _________________________ 14 __ 11 ___ 7 ______________0 ___ 5 __ 4 (best possible 4 4 4) ____________________________________________________________________ As of Kate (Aug 30) now three forecasts are impossible to verify but those three can still win the contest by hitting their best possibles. With Larry now a major, a fourth forecast would fall into this category. And with Mindy's arrival three more have drifted into the Cannot Fully Verify Narrows. Most can still win the contest though if they hit their best possibles. Nicholas did not add any new members to the "cannot fully verify" category but drew even with our lowest prediction of number of storms. We are still one short of the lowest number of hurricanes predicted, and had already seen one forecast passed by the number of majors with three others now level at 5. (Aug 22) If we assumed that one third of the season has occurred and two equal thirds lie ahead, the outcome would be 24 9 3 If we assumed that 40% of the season has now occurred but that the remaining 60 per cent would be twice as productive of hurricanes and majors, the outcome would then be 20 9 3 The mean of these two assumptions is 22 9 3. (Aug 27) If we now assume 45% of season has occurred and remaining 55 per cent would be 1.8 times as productive of hurricanes and majors, the new target is then 20 9 4.5 (Sep 2) If Larry became a major and the count was 12 5 3 and we assumed this was the halfway point of the season with an equal second half, the outcome would be 24 10 6. Only one forecast goes higher on named storms, several have higher H and M components. (Sep 8) The forecast models are not too bullish on additional tropical developments in this peak portion of the season so a more subjective outlook now might be around 21 11 5. Just my speculation though. -
Have been following this with interest, my hunch is that it will come in further west than many expect, over western Long Island. Intensity at that point might be marginal cat-1 TS boundary.

NOTES: Very few of the departures (errors) are negative so far (indicated by italic type), those of course can only increase with future changes in seasonal maxima. So in almost all cases these scores can still improve and all the totals could improve. The number in brackets after a few of the total scores are "total negatives" which represent the portion of the score already locked in. Only some of the better scores have this element. The number in brackets then also represents the lowest total score you can now achieve if your positive departures reduce to zero. Second place biodhokie has three of four stations at zero error currently, while leader tplbge has two on the right value with a total departure of 5. Nobody so far has a lower forecast than the actual values at DCA and RIC (for RIC there is still a field-wide three degree shortfall at 96 F, one (biodhokie) has a zero error now for DCA at 97F and there are several at 98F). Took a quick look at today's weather and it looks like none of the above will change today. -
