A hazardous weather outlook is in effect for Darien and the surrounding area beginning Wednesday through the weekend, according to the National Weather Service.

A few afternoon thunderstorms are expected Wednesday and the strongest cells could produce strong wind gusts. Low pressure moving up the coast Friday into early Saturday has potential to produce flooding rains. Exactly where the heaviest rains occur will be highly dependent on the low track, which remains uncertain.

As high pressure develops over the western Atlantic Ocean, the heat will return into Wednesday and Thursday for the tri-state area. Cloud cover and onshore flow won`t allow temperatures to drop much as lows will only be in the upper 60s and low 70s.

By Wednesday, a weak warm front makes its way northward through the area allowing skies to remain mostly cloudy. As high temperatures rise to the middle and upper 80s, some afternoon showers or thunderstorms are possible, especially toward inland areas away from the coast. Low temperatures Wednesday night will be in the upper 60s and low 70s. High pressure then briefly builds on Thursday allowing skies to become partly cloudy and high temperatures to remain in the middle to upper 80s.

Note: Darien’s beaches can close after a heavy rain impacts water quality. Darien beaches were closed July 2 due to more than an inch of rain falling in 24 hours.

The Darien Health Department checks water quality once a week throughout the summer. For more info on how the health department determines water quality visit here.
