A Flash Flood Watch was expanded this morning by the National Weather Service in Midland/Odessa, Texas, covering parts of southeastern New Mexico and western Texas.

Affected counties include Eddy, Lea, Gaines, Dawson, Borden, Scurry, Andrews, Martin, Howard and Mitchell, with potential flooding of rivers, creeks, low-lying urban areas and poor-drainage crossings.

In northeastern Florida, the First Coast News meteorologist reported a Flash Flood Warning in effect until 12:30 PM EDT for Nassau County, centered over Hilliard. Radar estimates indicate 2 to 4 inches of rain has fallen in the past hour, with localized amounts up to 3.5 inches. Additional rainfall of 1 to 3 inches could cause urban flooding, creek overflows and pooling on roadways.

The Weather Prediction Center also maintained a Slight Risk (Level 2 of 4) for excessive rainfall from eastern New Mexico into West Texas and the Plains for today. The outlook highlights the potential for 2-3 inch rain totals, especially where terrain and burn scars enhance runoff, leading to isolated flash flood threats.
