Flash floods can strike any time and any place with little or no warning. In flat terrain, distant rain may be channeled into gullies and ravines.
During a major rain storm, many of Westchester's parkways and roadways may become flooded.

Westchester County is vulnerable to hurricanes and tropical storms with its extensive coastline along the Long Island Sound and Hudson River. These storms, powered by heat from the sea, carry winds of at least 74 miles per hour and can cause extensive damage, especially to low-lying coastal areas.
While hurricanes are relatively rare to Westchester, some times a tropical storm can pack a lot of punch as well. High winds and torrential rains can cause heavy flooding and fallen trees and power lines. Residents throughout the county, especially those living in coastal communities, should have an emergency plan and know what they would do if an evacuation of the area were necessary.
Hurricane winds blow in a large spiral around a relative calm center known as the “eye.” The eye of the storm is generally 20 to 30 miles wide, while the storm itself may extend outward 400 miles. A single hurricane can last for more than two weeks over open waters and can run a path across the entire length of the eastern seaboard. August and September are peak months during the hurricane season that lasts from June 1 through Nov. 30.
