This Hazardous Weather Outlook is for South-Central Texas..

.DAY ONE...This Afternoon And Tonight.

Locations generally along and east of Interstate 35 and along the
Rio Grande will see afternoon heat index values of 102 to 107
degrees again today. Prolonged exposure to the heat and exertion
outdoors without proper hydration and other precautionary actions
may result in heat related illness.

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

Elevated heat index values will continue along and southeast of
the Balcones Escarpment and along the Rio Grande Wednesday, with
peak values ranging from 102 to 107 degrees during the afternoon
hours.

We are monitoring the remnants of what was Tropical Storm Harvey,
currently located near the Yucatan. Conditions are favorable for
re-development into a tropical cyclone Wednesday or Thursday over
the southwest Gulf of Mexico. There if growing confidence the
system will impact the Texas coast Friday into the weekend.
However there remains considerable uncertainty on exactly where
the system will move into the Texas coast and impacts inland
across South Central Texas.

At this time between 2 and 6 inches of rainfall, with isolated
higher amounts, are forecast across South Central Texas Friday
through the weekend. It should be stressed that there is the
potential for much higher amounts across South Central Texas if
the center of the potential tropical system tracks into the Lower
or Mid Texas Coast, and much lower amounts if the center tracks
into the Upper Texas Coast. These rainfall forecast amounts are
likely to change.

There is also the potential for tropical storm force winds inland
Friday into Saturday east of I-35. However, it is too soon to
determine exact wind impacts.

Stay closely tuned to forecast over the next day or two as greater
confidence and details emerge.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated.
