311 AM MDT Sun May 18 2025
...CRITICAL FIRE WEATHER CONDITIONS TODAY AND MONDAY FOR SOUTHERN
NEW MEXICO AND FAR WEST TEXAS...
.Jet streak of strong wind aloft crossing the Southern Rockies
will induce low surface pressure over the southern High Plains
this afternoon and again on Monday. Subsequent tightening of the
surface pressure gradient will increase winds area wide from the
west-southwest. Peak wind gusts to 45 mph over the high terrain,
gaps, and east slopes are expected. Very dry air remains in place
while winds increase, creating critical fire danger for southern
New Mexico and far west Texas. Recent dryness has increased fuel
ERCs back to above normal and any fires that develop have the
potential to spread rapidly.
