The severe weather poses significant risks, including potential tornadoes, flash flooding, and travel disruptions. Flooding has already caused delays on the Major Deegan Expressway and road closures on the Henry Hudson Parkway due to a fallen tree. Low-lying areas and locations with poor drainage are particularly vulnerable to flooding. Residents in basements are advised to move to higher floors, and drivers are warned not to enter flooded roadways. The tornado watch indicates favorable conditions for tornado formation, and residents should remain alert for potential tornado warnings.
