URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 288

The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
The Permian Basin of west central Texas
* Effective this Saturday evening from 600 PM until 1100 PM CDT.
* Primary threats include...
Scattered damaging wind gusts to 70 mph possible
Isolated large hail events to 1.5 inches in diameter possible
SUMMARY...Thunderstorms are expected to form and grow into multicell
clusters in the area immediately west of Midland, and then spread
east-southeastward through late evening. The storm environment will
favor damaging outflow gusts as the main threat, though the
strongest developing storms may also produce isolated large hail.
The severe thunderstorm watch area is approximately along and 75
statute miles east and west of a line from 25 miles north northwest
of Big Spring TX to 55 miles west southwest of San Angelo TX. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU8).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
