New York City and much of the Tri-State area are under a Flood Watch as forecasts predict slow-moving storms could bring up to 7 inches of rain, leading to a serious flash flood threat. Heavy rain is expected across the Northeast, with NYC and Philadelphia at the center of the storm activity. As conditions worsen, there is an increased risk of tornadoes and damaging winds, prompting travel advisories and warnings from officials including Governor Hochul. Residents are advised to exercise caution as multiple states face significant rainfall and the potential for localized flooding throughout the week.
