More rain is expected to cause potential flooding in the Lower Hudson Valley Monday after major thunderstorms Sunday.

The National Weather Service is warning New Yorkers could see some more hazardous weather, including possible severe thunderstorms which could bring high winds and flash flooding to already sensitive areas Monday afternoon and evening.

Some storm drains are already at capacity in Westchester after the county received nearly four inches of rain during a flash flood event around 6 p.m.

The sudden torrential downpours caused significant flooding in communities and major roadways near the Sound Shore like Mamaroneck and New Rochelle, but most of the rain damage was cleared up for Monday morning commuters by 6 a.m.

New Rochelle and Rye received the highest rainfall amounts in the Lower Hudson Valley, with 3.84 inches and 3.64 inches of rain, respectively. Rockland County also experienced heavy rains and ponding on roads but received around 2.25 inches of rain. Neighborhoods in Northern Westchester and Putnam County only appeared to receive around 2 inches of rain Sunday.

Neighborhoods in Connecticut and Long Island were hit with the most rain. Fairfield County saw approximately 10 inches of rain , mudslides and major flooding in some areas, while parts of Suffolk County received 7 to 9 inches near Commack and Stony Brook.
