UPDATE (6:30 p.m) The severe thunderstorm watch has been lifted. Rain expected to last into the evening according to the NWS.
Powerful thunderstorms are expected to bring strong winds and dump heavy rain on parts southern Westchester County this afternoon, according to predictions from the National Weather Service.
Harrison is currently under a severe thunderstorm watch until 9 p.m., but cities in other parts of Westchester are already under warnings.
The latest predictions say winds could reach 60 mph and storms could produce hail. Flash flooding is also possible, as the strongest storms could produce one to two inches of rain in an hour.
The storms are the result of a cold front moving into the area. Heat and humidity built up during the recent heat wave have created an unstable atmosphere, making storms likely, according to the NWS.
Residents are urged to secure loose items in their yards, stow umbrellas, and ensure drains and downspouts are clear of debris.
Remember if you can hear thunder you are close enough to be struck by associated lightning. Be mindful of weather conditions and take shelter in a sturdy structure is the weather conditions warrant such action.
