Drenching downpours from Tropical Depression Florence on Tuesday will increase the risk of flash, urban and small-stream flooding in the Middle Atlantic and New England. Still, flooding should not be widespread as the system picks up speed after its crawl through the Carolinas. A few severe thunderstorms may develop in parts of the coastal Middle Atlantic.

River flooding is projected to worsen across the Carolinas and into southern Virginia. Rivers from the middle parts of these states to the southern Appalachians will crest in the next day or so. Many rivers closer to the coast may not crest for another week and could remain above flood stage until the end of the month. This means that many roads may remain closed, and some people may be out of their homes until later in autumn. A few storms on the tail end of the tropical system will affect the Southeast and Gulf coasts. Any storm that drenches saturated ground could result in flash flooding.

A nontropical storm will bring rain and thunderstorms to parts of the northern Plains and the Upper Midwest. Since much of the region has been dry in recent days, widespread flooding is not expected. Much of the West will be sunny and dry. Some downpours will move into southern New Mexico and Arizona.

Focus: Rainy Spell for the Upper Midwest

Storms are projected to move from the northern Plains to the Upper Midwest this week, which will result in significant rainfall. The heaviest rain will stretch from northern Nebraska to the northern Lower Peninsula of Michigan.
