URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 107
NWS Storm Prediction Center Norman OK
1025 PM CDT Sat Apr 1 2017
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
South-central and southwest Texas

until 600 AM CDT.
* Primary threats include...
A couple tornadoes possible
Scattered large hail and isolated very large hail events to 4
inches in diameter possible
Isolated damaging wind gusts to 70 mph possible
SUMMARY...At first, a pair of thunderstorms moving out of Mexico
will pose a threat for large, damaging hail and severe gusts. With
time, additional storm development is expected on either side of the
international border, moving into an environment increasingly
favorable for a tornado or two as well. See SPC mesoscale
discussion 396 for initial meteorological reasoning.
The tornado watch area is approximately along and 45 statute miles
either side of a line from 20 miles west northwest of Del Rio TX to
45 miles east southeast of Junction TX. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS
WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and 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.
&&
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 4 inches. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 550. Mean
storm motion vector 24025.
