A powerful storm brought dangerous flooding and travel disruptions to the East Coast on Monday, knocking out power to over 620,000 homes and businesses in the Northeast. At least 4 people have died due to the storm. Heavy rainfall of 2-4 inches triggered widespread flooding across the region, submerging cars and trapping drivers on flooded roadways in states like New Jersey and Connecticut. Rivers in the Northeast are anticipated to reach their highest levels on Tuesday, with expectations that they will recede from flood stages soon after.
