Hurricane Humberto, Invest 94L Threaten East Coast

A broad swath of the U.S. will see unsettled weather beginning Thursday with periods of rain that could produce moderate to heavy downpours, isolated damaging‑wind storms, and pockets of localized flooding, especially in poorly drained areas over the weekend. The D.C. area is forecast to see steady, occasionally heavy rain Saturday (highs in the low–mid 70s) before drying and turning sunnier Sunday into Monday with temperatures in the upper 70s. Across the Northeast, clouds and a few overnight/early‑Sunday showers should clear for warm, mostly sunny conditions Sunday–Monday with highs in the upper 70s to low 80s, while Long Island and other Mid‑Atlantic areas trend cooler into next week. Hurricane Humberto has strengthened and, along with a developing Invest 94L that could become a tropical depression, is producing dangerous swells and rip currents and may threaten the Bahamas and Carolinas with additional rainfall next week. Interior regions will trend drier and slightly cooler under building high pressure, but outdoor events and coastal activities should monitor forecasts for hazardous surf and possible flash or street flooding.
