Residents in Upstate New York face significant risks from severe weather conditions, including tornadoes, high winds, hail, and flooding. Areas that experienced heavy rainfall earlier, such as northern Onondaga County, are particularly vulnerable to flash flooding. Tornadoes could cause widespread damage with winds up to 110 mph, while hail and wind gusts may lead to property damage and hazardous travel conditions. Communities in Cayuga, Onondaga, Seneca, and Steuben counties are under tornado warnings, urging residents to take immediate shelter. (Source: Syracuse.com, WSYR NewsChannel 9)
