The focus of the most intense weather is shifting northward. By Monday, the Northeast region will bear the brunt of the storm's impact. Major metropolitan areas such as New York City and Boston are particularly vulnerable. The combination of heavy rainfall and urban infrastructure means that low-lying areas are at a heightened risk of experiencing flash floods. The forecast indicates that this severe weather could lead to significant disruptions for commuters and travelers, affecting daily routines and potentially causing delays across various modes of transportation.
