...FLASH FLOOD WARNING WILL EXPIRE AT 515 PM MDT THIS AFTERNOON FOR 
SOUTH CENTRAL DONA ANA AND WESTERN EL PASO COUNTIES...

The heavy rain has ended. Flash flooding is no longer expected to 
pose a threat, but flooded roadways are still a hazard. Please 
continue to heed remaining road closures. A flood warning continues 
due to so much water ponding on the roads and catch basins.

Heavy rain is still possible this evening so a Flash Flood Watch 
remains in effect until 600 PM MDT Sunday for portions of New Mexico 
and southwest Texas.
