BAY SHORE - Many residents in Suffolk County are dealing with the aftermath from yesterday’s historic flooding.

The Town of Islip is filled with flooded streets, yards, basements and damaged cars.

Both Islip and the Town of Babylon have declared a state of emergency.

No one expected over 13 inches of rain, and Suffolk was never designed for a monsoon, according to Suffolk County Executive Steve Bellone.    

"The drainage systems in the county, and you'd find similar numbers throughout the municipal systems, are designed to sustain a five-inch storm over a 24-hour period. This was 13 inches within several hours," said Bellone.

Islip crews continued to pump water from flooded streets overnight.    

A Command Center from the State Insurance Department will be at Islip Town Hall at 8 a.m. to provide assistance to people with flooded homes and businesses.
