Breakfast Brief: Multiple flood risks to monitor

Debby will continue to bring an onslaught of heavy, tropical downpours to the Southeast with potentially catastrophic impacts. Flooding rain will also affect portions of the Northeast on Tuesday.

Deep tropical moisture from Debby will spread north and interact with an approaching cold front, sparking showers and thunderstorms. These storms are capable of producing very heavy rainfall, with widespread totals of 1 to 2 inches expected from Maryland to Massachusetts, affecting most of the major metro areas along the I-95 corridor. Locally, much higher rain totals are likely, and isolated flash flooding is anticipated in these areas.

A cool air mass has entered the north-central U.S. and will continue spreading across the Great Lakes, Ohio Valley, and into the interior Northeast today. Temperatures in these regions will run 10 to 15 degrees below average, making it feel more like early fall than mid-summer.

While cooler weather is coming to the north, central and western U.S. regions will continue to experience extreme heat. The Central and Southern Plains could see daily highs of 105 to 110 degrees, with some locations breaking records through Thursday. In the Southwest, dangerous heat will persist, with some low-lying desert areas exceeding 110 degrees.

Debby made landfall near Steinhatchee, Fla., on Monday morning as a Category 1 hurricane, bringing winds up to 80 mph and a dangerous storm surge. Although the storm's winds have decreased since landfall, the potential for deadly impacts from flooding remains through Saturday. Potentially historic rainfall is possible with this cyclone.
