This Hazardous Weather Outlook is for portions of south central
New Mexico, southwest New Mexico, and southwest Texas.

.DAY ONE...Today and Tonight

Scattered to numerous showers and thunderstorms are expected to
develop once again this afternoon over the mountainous terrain of
southern New Mexico. Locally heavy rainfall will be possible,
especially for the east slopes of the Sacramento Mountains and
Gila Wilderness. Flash flooding will be the primary hazard. Rain
amounts in excess of 2 inches per hour may quickly make back
country roadways and low water crossings impassable. Hikers and
campers should take proper precautions from the threat of
lightning and running water.

More isolated storm coverage is expected over the lowlands later
this evening, with localized flooding and gusty outflow winds up
to 40 mph possible. Loose outdoor objects should be secured near
thunderstorms, and people should go indoors when thunder is heard.
Light rain showers may linger into the early morning hours.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

A daily chance for showers and thunderstorms will continue on
Tuesday and Wednesday. Thunderstorms will focus over high mountain
terrain, with more isolated activity in the lowlands. The main
threat will continue to be locally heavy rain and flooding,
although a few strong storms will be possible on Tuesday,
producing gusty winds and small hail. Thunderstorm coverage will
diminish Thursday and Friday as drier air moves into the region
before returning next weekend.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed, however SKYWARN spotters
are encouraged to relay reports of severe weather and flooding to
WFO EPZ when it occurs.
