Locally Heavy Rainfall Possible Over the Four Corners; Critical Fire Weather Conditions in the Great Basin
Monsoon moisture will result in locally heavy showers and thunderstorms over the Four Corners region, which could lead to flash flooding. While, critical fire weather threats are expected for much of the Great Basin, from dry and windy conditions. Finally, Tropical Cyclone Humberto remains well offshore of the Southeast, but rip currents and heavy surf are expected from Florida to the Carolinas.
