The NWS warns of flash flooding in small creeks, streams, urban areas, highways, streets, underpasses, and other low-lying or poorly drained areas. Localized flash flooding is possible, particularly in urban centers if heavy rain bands develop. The risk is heightened for drivers, as most flood-related fatalities occur in vehicles. Residents in the affected areas should remain vigilant, especially in regions south of the Massachusetts Turnpike, where the heaviest rainfall is expected.
