1823: A strong category 1 or low category 2 hurricane struck near New Orleans, Louisiana and went toward Baton Rouge. Its strongest impacts occurred west of New Orleans.

 

 

1928 - Hurricane San Felipe crossed Puerto Rico resulting in the highest winds, the heaviest rains, and the greatest destruction in years. The hurricane produced much damage in the Virgin Islands, and later hit the Bahamas and Florida. (David Ludlum)

1934: The mercury soared to 92 degrees at Seattle, WA, a record for September. (The Weather Channel)

1944: Hampton Roads saw winds of 72 mph gusting to 90 mph. Richmond had 3.26 inches of rain on the 13th. Winds of 134 mph sustained with gusts to 150 mph lashed Cape Henry a wind record which remains standing today for the state.Virginia Beach saw the pressure fall to 28.80". Rainfall from the storm caused a flood of record at State Farm on the James river (26.4 feet).Damage totaled $2.5 million. Forty-six perished. This system was the first time that air force reconnaissance air craft were used to monitor a storm threatening the East Coast. Rec. Major east coast storm Sep. 13-15th

1944: The destroyer USS Warrington was sunk by the Great Atlantic Hurricane 300 miles east of Cape Canaveral, Florida. 247 men were lost in the tragedy.  

1978: Little Rock, Arkansas saw 8.10 inches of rain which caused major flash flooding. Ten people were killed. 

1984 - Hurricane Diana, after making a complete loop off the Carolina coast, made landfall and moved across eastern North Carolina. Diana deluged Cape Fear with more than eighteen inches of rain, and caused 78 million dollars damage in North Carolina. (Storm Data)

 

1987 - Showers and thunderstorms produced heavy rain in the northeastern U.S. Flooding was reported in Vermont, New York, Pennsylvania and New Jersey. Greenwood NY received 6.37 inches of rain. A dike along a creek at Prattsburg NY gave way and a two million dollar onion crop left on the ground to dry was washed away. The prolonged rains in the eastern U.S. finally came to an end late in the day as a cold front began to push the warm and humid airmass out to sea. (The National Weather Summary) (Storm Data)

1988 - Hurricane Gilbert smashed into the Cayman Islands, and as it headed for the Yucatan peninsula of Mexico strenghtened into a monster hurricane, packing winds of 175 mph. The barometric pressure at the center of Gilbert reached 26.13 inches (888 mb), an all-time record for any hurricane in the Carribean, Gulf of Mexico, or the Atlantic Ocean. Gilbert covered much of the Gulf of Mexico, producing rain as far away as the Florida Keys. (The National Weather Summary) (Storm Data)

1989 - Unseasonably cool weather prevailed over the Central Plains Region, with a record low of 29 degrees at North Platte NE. Unseasonably warm weather prevailed across the Pacific Northwest, with a record high of 96 degrees at Eugene OR. Thunderstorms over south Texas produced wind gusts to 69 mph at Del Rio, and two inches of rain in two hours. (National Weather Summary)

1993: A strong, winter-type storm moving through the Rockies and the western Plains produced record early season snowfall. Denver, Colorado recorded 5.4 inches of snow for its greatest snowstorm ever for so early in the season, after reaching 92 degrees the day before. The same record was also set at both Cheyenne, Wyoming and Scottsbluff, Nebraska with 5.5 and 2.5 inches of snow, respectively. Along with the snow came record lows including: Cheyenne, WY: 29°, Rapid City, SD: 29°-Tied, Colorado Springs, CO: 32°-Tied and Denver, CO: 33°. (Ref. AccWeather Weather History)

1994: Microburst winds of 100 mph removed the roof above 8 classrooms of the Littleton Elementary School in Cashion, AZ; 8 children/1 teacher were injured. The same storm littered the ground with golf ball-size hail and knocked down a mile-long stretch of power poles. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA)

1996: Hurricane Fausto moved across Baja on Friday night the 13th and continued moving north-northeastward, striking mainland Mexico early Saturday morning. (Ref. AccWeather Weather History)

1998: Heavy rain of 5 to 12 inches fell over portions of extreme southeast Kansas. Unofficial reports of rainfall amounts as high as 14 inches was reported in Bourbon County, Kansas. The hardest hit areas were along the Marmaton River in Bourbon County including Ft. Scott. The highest estimated stage of the Marmaton River at Ft. Scott reached 50.05 feet on the 14th which is the second highest stage ever recorded. (Ref. Wilson Wx. History)

1999: Hurricane Floyd on the verge of Category 5 status steamed steadily westward about 250 miles east of Miami. Forecasters warned that Floyd was much more dangerous than 1992's Hurricane Andrew due to its size. (Ref. Wilson Wx. History)

2007: Hurricane Humberto made landfall just east of High Island, TX in the McFadden National Wildlife Refuge. Hurricane Humberto had maximum sustained winds near 90 mph and a minimum pressure of 985 millibars or 29.09 inches of mercury. Humberto made history due to its rapid intensification from a tropical depression the morning of September 12th, to a hurricane early on this date, as no other hurricane has ever strengthened so quickly close to landfall. Damage was estimated near $60 million dollars. Only five other storms in Atlantic Basin history has grown from a depression to a hurricane within 24 hours: Arlene & Flora in 1963, Blanche in 1969, Celia in 1970 (from depression to a Category 3) and Harvey in 1981. (Ref. Wilson Wx. History)

2008: Hurricane Ike made landfall as a Category 2 storm near Galveston, Texas. 

2008: Hurricane Ike made landfall around 0700z along the northern end of Galveston Island, TX as a strong Category 2 storms with maximum sustained winds of 110 mph and a minimum central pressure of 28.14 inches of mercury. Prior to landfall, Ike covered an extensive area of the Gulf of Mexico with the largest radii of hurricane-force winds: 125 miles out from the center and tropical-storm force winds: 275 miles out from the center, ever measured. Much of Galveston and nearby coastal towns were left in shambles, and storm-surge damage extended well east into Louisiana. Ike resulted in 103 deaths across Hispaniola, Cuba and parts of the United States Gulf Coast and total damage at $32 billion dollars. (Ref. Wilson Wx. History)

2014: The 3rd of the top 10 US weather events according to Weatherwise magazine was the Boulder Colorado flash flood of September 9th through the 16th. This deluge dumped more than 9 inches of precipitation in 24 hours and 14 inches in four days on Colorado foothills unleashing furious flooding on Boulder and the surrounding towns. It damaged and destroyed 1800 homes, and washed out hundreds of miles of road, and cost $2 billion. (Ref.Weatherwise May/June 2013 page 15)

2017: Irma started on August 30th and reached its peak on Sep. 6th and hit FLA. on Sunday night Sep. 10th, 2017. On September 6, Irma reached its peak intensity with 185 mph (295 km/h) winds and a minimum pressure of 914 hPa (27.0 inHg), making it the strongest tropical cyclone worldwide so far in 2017. Another eyewall replacement cycle caused Irma to weaken back to a Category 4 hurricane, but the storm attained Category 5 status for a second time while making landfall in Cuba. After dropping to Category 3 intensity due to land interaction, the storm re-intensified to Category 4 as it crossed warm waters between Cuba and Florida before making landfall on Cudjoe Key with maximum sustained winds of 130 mph (215 km/h). Irma dropped back to Category 3 by the time it made a second Florida landfall on Marco Island

2017: The NWS Office in Reno, Nevada, issued their first tornado warning since July 21st, 2014. 


2018: Hurricane Florence was a powerful and long-lived Cape Verde hurricane, as well as the wettest tropical cyclone on record in the Carolinas and the ninth-wettest tropical cyclone to affect the contiguous United States. The sixth named storm, third hurricane, and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30, 2018. Steady organization resulted in the formation of a tropical depression on the next day near Cape Verde. Progressing along a steady west-northwest trajectory, the system acquired tropical storm strength on September 1, and fluctuated in strength for several days over open ocean. An unexpected bout of rapid intensification ensued on September 4– 5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale with estimated maximum sustained winds of 130 mph

Strangely Upton's bullseye from yesterday looks to be the area that will see the lowest totals

NYC isn’t considered one of the local warm spots these days due to the artificial cooling from the trees. So the mid 80s will likely be from around Philly to perhaps Newark. This record breaking 600 dm ridge really moderated the cool down which was expected to follow for late September.

 

New run

Old run

 

 

 

 

considering nyc is one of the warm spots for overnight lows what a launching pad to be one of the warm spots for high temps unless you only count central park and not other parts of the city where they are one of the warmest spots in the tri state area..

I almost wish Upton wouldn't go with a map like this when it's obviously a convective system. But yesterday the split screw area somewhere was pretty obvious. What a summer for coastal CT deluge. 

[Brian5671]

Absolute destruction here-masssive flooding everywhere

Agreed. I’m smack dab in the middle of the donut hole. Had about 10 minutes of torrential rain, and right now the sun is peaking out. Maybe the precipitation to the west will pivot through 

[ForestHillWx]

Heavy rain continues in this part of Morris. 

[weathermedic]

.32 so far here in southern Brooklyn

[lee59]

Ct. coast looks to be the bullseye so far, not to much here, .27 of an inch.

Yeah, this is the heaviest downpour since the summer with plenty of street and parking lot flooding in my area. Southern CT has really been the focus of the heaviest rains. The complete opposite of last summer when we had record low rainfall.

The lows in NYC run cooler than the surrounding urban sites like LGA and EWR. So the tree growth is probably lowering the minimum temperatures also to some extent. In the old days the NYC minimums would average closer to or warmer than those sites before the excessive tree growth.

1.85" here. Glad to get a nice soaking for the vegetable garden! 

[donsutherland1]

Bridgeport has now received 3.45" of rain today. That is the fourth highest daily rainfall record for any day in September. It is also Bridgeport's heaviest one-day rainfall since the September 1, 2021 deluge dumped 5.77" of rain.

Heavy rain now. Hopefully the seed I laid down yesterday doesn’t all wash out. 

Saw that a flash flood warning was posted for southeastern Morris County down near Long Hill Township/Chatham. 

Seems most areas seeing reasonable totals in the .5-1" range thus far.  The excessive totals are more isolated.  

Hope your grass seed made it.  Frustrating to have it wash away.  Been there done that.

These are amounts as of about 9:00 a.m. with the event still ongoing.

You've had your share of "jackpot totals" this Summer.

[forkyfork]

today's blast from the past. imagine fall starting in august

[donsutherland1]

So far, both Bridgeport (1.18") and Islip (1.13") have had an hourly period today with 1" or more rainfall. New Haven's rain measurements are again not being recorded.

The modeling that targeted CT/LI nailed the max totals.

[lee59]

Looks like many along the Ct. coast have received some 3 to 6 inches of rain

[gravitylover]

Just hitting 1" now. 

[s2sailorlis]

My Ambient station report.  In 10 minutes had a lake in front and stream side of house,  some nuisance garage flooding..  Quick Dams are great I have a dozen of them… Fairfield, CT

[Snowlover11]

Nice drink should get close to an 1”

[donsutherland1]

Islip has now picked up 2.31" of rain. That breaks the daily mark of 1.82" from 1971. Rain is falling heavily there.

[BobbyHolikWillFindYou]

Up to 3.74 now. This is a basement filler for eastern Passaic County.
