This area has been one area that has been hit especially hard lately. Torrential rains which resulted in flooding in CT will move into the warned area shortly. Flash flooding may begin and could become significant quickly. https://t.co/y1BTQZ8X0N

[Wed] A slow moving cold front will bring showers, downpours, and embedded T-Storms to southern New England through early Thursday morning. An additional 1-2" of rain may result in a renewed risk for urban, poor drainage and flash flooding given very wet antecedent conditions pic.twitter.com/gX5ZbKAcWO

⚠️ Flood Watch – 11 AM Today through 7 AM Thursday

Know the difference between a 'watch' & a 'warning' when it comes to flooding. A watch means conditions are favorable for flooding to occur, while a warning means it is currently happening or is about to happen #MAwx #CTwx #RIwx pic.twitter.com/CPjJRrC1ww

HURRICANE #LEE
Will make it's closest pass to SNE on Saturday as a weakening CAT1 hurricane transitioning to a post tropical storm w/ a large wind field. Cone has ticked west- TS force (sustained) winds are likely on Cape Cod with large waves 20' just offshore Fri night #WCVB pic.twitter.com/KXaG6KmVPr

NEXT 7 DAYS
After today's downpours and storms the humidity drops way down. Impacts from #hurricaneLee Friday night-Saturday with strong winds at the coast and some wind and rain inland. Large waves and rip current risk begin today and last thru the weekend. Clearing Sunday #WCVB pic.twitter.com/u8OxdQIuDx

Flood watch up again today, Lee a coastal concern Saturday, especially Cape/Islands. pic.twitter.com/nYyYiuagm8

Flood watch up today. Localized downpours dropping a quick 1-2" for some. Few localized higher totals possible. pic.twitter.com/irp7woOQgV

Closest pass to New England with Lee is Saturday morning/midday. Cone is for the eye/center of the storms. Impacts will extend well away from center. pic.twitter.com/ZGBfgT6p4t

As max sustained winds decrease as it moves north, the wind field in Lee actually expands. Even a track 100 miles offshore would produce gusts 60-70+mph across the Cape/Islands. pic.twitter.com/SC8vFSXyzs

High tide Saturday is around 1pm. Big wave action and high rip current risk is a lock. Track will determines the amount of coastal flooding/erosion we'll get. More eastern track = less impact, more western track = significant impacts with coastal concerns/wind. pic.twitter.com/PshG5MAlvR

— Chris Lambert (@clamberton7) September 13, 2023

The weather today will be high impact with localized flooding and the chance for a severe t-storm with wind damage or an isolated tornado. Stay alert this afternoon. @Boston25 pic.twitter.com/e06WSjR6iC

FLOOD WATCH starts at 11 AM for slow t-storms/downpours. I expect some, if not several, problem spots this afternoon & during the evening commute. NEVER DRIVE THROUGH A FLOODED ROAD. @boston25 pic.twitter.com/LBVusldbOy

Here’s the latest #HurricaneLee track as of 5 AM today. That track is about 125 miles off #CapeCod Saturday, close enough for some rain & wind locally. Estimates will start coming into focus over the next 24 hours. @boston25 pic.twitter.com/wCMOXToYqi
