Millions under flood watch in Northeast, Mid-Atlantic due to heavy rain from plume of tropical moisture
SUMMARY
A plume of tropical moisture and a stalled frontal boundary are causing heavy rainfall across the Northeast and Mid-Atlantic regions from South Carolina to New England through the weekend. Despite not developing into a tropical system, the weather system is expected to bring significant rainfall, prompting flood watches for 45 million people along the Interstate 95 corridor from Boston to the Carolinas. Rainfall totals of 2-3 inches are likely, with isolated areas possibly receiving up to 5 inches, posing a risk of flash flooding. The heaviest rain is forecasted for northeastern Maryland, northern Delaware, southeastern Pennsylvania, and southwest New Jersey by Friday night. The weather is expected to improve with sunny conditions returning on Sunday.
