This Hazardous Weather Outlook is for southern Arkansas, for
northern Louisiana, for eastern Texas and southeast Oklahoma.

.DAY ONE...Today and Tonight...

A Heat Advisory is in effect today with our four state area
temperatures this afternoon averaging in the upper 90s. When the
humidity is factored in, the feels like or heat index temperature
ranges will be from 105 and 110 degrees. The best practices for
work or play in this kind of heat include wearing light colored
and light weight, loose fitting clothing; drinking plenty of
water before, during and after exposure to the heat; also by
limiting the time spent outdoors or at least taking more frequent
shade breaks, or some time in the A C. There will be a chance for
afternoon and early evening showers and thunderstorms, coverage
will be isolated in our North to scattered across our South.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

The heat will continue into midweek with the Heat Advisory in
effect through Wednesday. Otherwise, scattered showers and
thunderstorms will be on the up tick on overall coverage into the
weekend. A weak front will approach and weaken the heat ridge in
the upper air. We can also expect that a weak low area of broad
low pressure over the Gulf coast will help to keep the air muggy,
good for developing some heavier rainfall totals.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators and storm spotters will not be needed through tonight.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency, call 9 1 1.
