…A FIRE WEATHER WATCH HAS BEEN ISSUED FOR ALL SOUTHERN NEVADA FIRE
WEATHER ZONES FROM MONDAY MORNING THROUGH EARLY TUESDAY MORNING…

.DISCUSSION…Dry, calm conditions will continue today and Saturday as well as a gradual increase in temperatures 5-8 degrees above seasonal averages. No changes made to the Fire Weather Watches, though expected initial impacts at this time are trending a little later – more into the late Sunday into early morning hours of Monday time frame.

Weekend and into the start of the work week, fire weather concerns ramp up as gusty conditions and low relative humidity’s take over.
Fire Weather Watch issued Sunday afternoon through late Monday night for Inyo County & issued Monday afternoon through late
Monday night for southern Nevada.

NONE NONE

Flash Flood Codes: GREEN: NONE YELLOW: LOW ORANGE: MODERATE RED: HIGH

SPECIAL NOTES:

DAILY FUELS/FIRE POTENTIAL:
Very warm and dry conditions will keep the large fire threat slightly elevated across the area through Saturday. The best chance for a large fire will be on Sunday when windy conditions combine with the warm and dry conditions. Extreme fire behavior will be likely on any existing or new fire in windy locations Sunday. The warm and dry conditions will also cause the dead fuels to dry out significantly by Sunday. Light winds along with below normal temperatures and humidity above critical levels will cause the potential for large fire to become low Monday through the end of next week. Moderate initial attack activity will continue across the region through Sunday and then expect light IA activity Monday through the end of next week.

Disorganized showers and thunderstorms located about 1600 miles west-southwest of the southern tip of the Baja California peninsula are associated with a tropical wave. Only some slight development is

* Formation chance through 5 days…low…10 percent.

Another tropical wave located several hundred miles south-southwest of Acapulco, Mexico, is also producing disorganized showers and thunderstorms, mainly to the west of the wave axis. Some slow development is possible into next week while the system moves generally westward at 5 to 10 mph.

* Formation chance through 48 hours…low…10 percent.

* Formation chance through 5 days…low…30 percent.

An area of low pressure is expected to form west of the coast of Central America over the weekend.
