This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma and northeast Texas.

.DAY ONE...Tonight...

Scattered showers and thunderstorms will be possible today across
the four region area due to the effects of Tropical Storm Harvey
still located well to our south. Daytime heating will be limited
due to extensive cloud cover, but a few stronger bands of heavy
rainfall could materialize during the afternoon. Otherwise, no
hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

The track of Harvey is still somewhat uncertain through next week,
but rainfall amounts are expected to increase across our region by
the middle and latter part of the week as Harvey finally begins to
shift farther north and east. Additional rainfall totals next week
of three to six inches with isolated higher amounts close to eight
inches are possible across much of east Texas and north Louisiana
with enhanced sea breeze bands through mid to late week. This may
pose a flash flooding potential, but the uncertainty with Harvey's
eventual track makes this threat still somewhat unclear at this
time.

.SPOTTER INFORMATION STATEMENT...

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