Here's the latest Tropical Storm forecast for the Ark-La-Tex from KSLA News 12 Meteorologist Kevin Roth:

Isaac is weakening. Isaac mostly has been moving toward the north, northwest -- more toward the north than the west. That's good news for the ArkLaTex because the weakest part of the storm is its western part, which is where the ArkLaTex will be in Isaac's path if it continues north.

Here is where Isaac is going:

  • 7 a.m., Alexandria, winds at 45 mph;
  • 7 p.m., Shreveport, winds at 35 mph;
  • 7 a.m. Friday, north of Texarkana, Ark., winds at 30 mph

Isaac will be leaving southwest Arkansas by Friday night.

Tropical Storm Isaac continues spinning through Louisiana, bringing heavy rains and a maximum sustained wind speed of 50 miles per hour. The eye of the storm is currently just northwest of Baton Rouge, tracking slowly to the NNW towards the ArkLaTex. Conditions through the ArkLaTex will continue to worsen through the morning and afternoon hours, beginning in Northwest Louisiana.  

A dry, continental air mass has started to work into Isaac's circulation, which is limiting the rainfall amounts on the western side of the eye. This will help limit the flash flood danger, but most of the ArkLaTex remains under a flash flood watch regardless. 

A weakened Isaac will bring sustained winds between 20 and 30 miles per hour, with gusts reaching higher. Power outages have already been reported in Natchitoches and Bossier Parishes, and more are expected this afternoon.  

Conditions will begin to improve late tonight and through the day Friday.
