I can't see this going truly extratropical before Friday s of SC, but it could be hybrid by 36h. Wasn't there a debate about a possibly too-early call on Sandy being e.t. before NJ landfall? It would only confuse the public who would not get the spreading out wind field concept, personally I think they should retire the whole concept, if it's a hybrid or e.t. storm doing damage then keep issuing advisories until it's not doing damage. Now Kirk is definitely e.t. and has been for 24 ... and it's almost below damage creating criteria (wind gusts in nw Spain were 65-70 on very exposed rocky cliffs and look to be around 60-65 in western France).

Weakening like Tom Brady after 40?

I recall with Katrina there was a 15-20 ft surge (not all of it went into L Pontchartrain but enough did so, to stress the levees). But also I recall a 46' wave report about 30 miles east of the track -- so I would urge people to consider that south of landfall, if the hurricane is still at least cat-3, similar results are possible and 10-15 feet of surge could prove to be conservative, with battering waves on top of a (let's say) 15 to 18 ft surge. I am still leaning towards a relatively northward landfall (Clearwater area) but there's no plausible "good" landfall option at this point.

Japan has taken over tracking Super Typhoon Milton.

I would say track will start to edge slightly north of due east to avoid a landfall on Yucatan but with some of the core scraping along the coast briefly. At some point probably 18-24 hrs from now, possible cat-5 intensity and 910 mb central pressure. Gradually reduces to cat-3 by landfall at a point 25-50 nw of Tampa Bay.

Milton brings count to 13/8/3 and I edited table above for 13/9/3 as per guidance. (Oct 6 _ count is now 13/9/3 and table is now based on 13/9/4 as guidance strongly suggests further intensification). If season ended 13/9/3 scores would be Retrobuc 98.0 and wkd, tae laidir 97.5. Currently next in scoring is Ed Snow and Hurricane Fan at 90.5; KWx is 86.5 and dww is 88.5. If season ended 13/9/4 scores would be wkd, tae laidir 98.5, and Retrobuc 96.0 13/9/4 _ (Ed Snow and Hurricane Fan at 91.5; KWx is 87.5 and dww is 87.5) Top half of table need more storms to start scoring ... 24 (error 11) storms gives an error deduction of 66 (net score 34) so basically if your forecast was 25 or less and you have a reasonable forecast of H and M, your score is positive. (storm errors count 50% relative to H and M errors) Will get into scoring details later in OCT ... looks like 16/10/4 could be a target, if so, contest winner would be Ed.

Kirk brought count to 11/7/3 and Leslie to 12/7/3, very likely to go (edit now is) 12/8/3 (and probably not 12/8/4) so will edit "rest of season forecast" table several posts back now, based on 12/8/3. Next edit will also go forward to latest post. Edit is now added to post ... Oct 6 _ new edit for Milton (1/1/1 is being added now) ... count will be 13/9/4 Oct 19 _ Nadine, Oscar boost count to 15/10/4. Nov 3 _ Patty to 16/10/4 and edit for PTC 18 being at least a TS, potential count 17/10/4. Nov 6 _ Rafael now brings count to 17/11/5 As a scoring post contains following info, it will now be deleted, see Nov 4 post as edited for updates.

Extended summer stormlover74 future snow hole banter thread 23

There are some encouraging signs. But I actually dropped by to remind NYC people to enter forecast contest on time. -
Did Randy ever post about his experience in GA? I guess the worst of it went east of where he was (if he went)?

There is enough time to reach cat-4, I don't think cat-5 was ever a strong option. I will say cat-4 by 21z and either cat-4 to landfall or just back to top end cat-3 at landfall which I currently think will be 03z near St marks NWR to western Taylor co. Track will place western eyewall over TLH around 05z and very close to stormtracker's proposed location 09z and near or just east of ATL by 12-15z Friday. For a min pressure will go with 947 just before landfall. (935 is probably limit for min SLP) 40/70 I wanted to read your assessment but link was broken when I tried, this is perhaps why a post was deleted? Is my guess above close to yours? If not are you less intense and further east? That was my feeling as to bust direction, not stronger and not west of Carrabelle for landfall. Still 30% prob direct hit TLH.

Alberto (1994) dropped 24" rain in central GA. (near macon, severe flood damage) Will post on main thread also ... There is enough time to reach cat-4, I don't think cat-5 was ever a strong option.

As to RI potential, 'cane is not quite totally past land interaction and situation will probably explode after 06z and in particular when center is between 25 and 27 N tomorrow. A lot more effective energy inflow can take place as it gets further from land and inflow is coming from tropical Atlantic with Cuba no longer a partial obstacle to inflow. That will soon be the case. I would look for steady pressure falls after 06z, just slight falls to then.

With regard to situation over GA now, a frontal boundary runs from about 30e ATL to s.w. GA and will become q.s. overnite into Thursday, as hurricane approaches it will be pushed back to the west 20-40 miles and will be focus of exceptionally heavy rainfalls in 10-15 inch range (closer to 5-10 inch warmer air mass over e, s GA). I think the forecast for ATL, CSG and over towards Warner Robins (where Stormtracker is going, Bonaire is a suburb) needs to be along lines of all hell will break loose later Thurs after intermittent heavy thundershowers now to 18z, intervals of torrential wind-blown rain, frequent lightning, embedded tornadic wind streaks with gusts to 100-120 possible (outside of those, 80-100). It will only die down a bit when remnant low gets past ATL. That frontal boundary is probably going to stall overnite and edge back west as 'cane approaches landfall. Temps will be 66-69F on west side and 77-81 on east side. Imagine also upsloping all of those frontal dynamics into southern Apps. Nasty.

Yikes, cane will be ramping and passing just to your west by 9 pm to midnite, I would not be too confident flight will take place, is it an airline or charter? I am no coward but I would seriously consider postponing/not going. 25% chance it goes a bit too far west to produce worst case conditions (which could be SSE 50G75, 6-8" of rain and local tornadic windstreaks).
-
Table of storms (two posts back) still needed to verify forecasts is updated for likely events taking Helene to major next day or so. Also Isaac now a TS (edit _ and now a 'cane, not progged to be very strong). Also we now welcome Joyce, predicted to remain a TS. At 10/6/2 season if 70% done will end at 13/9/3 so almost all forecasts need a strong OCT-NOV to stand any real possibility of contest success now. A 5/4/2 Oct brings it to 15/10/4 and a 2/1/0 NOV to 17/11/4, so even stronger actual results would be needed by most of us.

Storm is near wtere Wilma set a record for rapid intensification in Oct 2005. Paths diverged afterwards (not expecting as fast RI this one, RI will be late Wednesday 26N or so)
-
I am expecting an over-performer (RI) and possibly cat-4 by 26-27 N (landfall 29N cat-3). East-west wobble factor (0.2-0.3 deg) is likely to play as max east displacements midnite, and max west mid-day, given moon's present orbital position. Strong n max declination peak at present will decrease over 3 days, it does add tidal range to coming period between F and new.
