EAST TEXAS (KTRE) - Hurricane Isaac has now weakened into a tropical storm as it slowly moves through southern Louisiana.
Isaac will continue its weakening trend as it moves northwest through central Louisiana on Thursday. By the time we head towards Thursday evening, Isaac will be downgraded even further, this time, to a tropical depression.
It now appears Isaac will track through Louisiana, but could get close to the state line on Thursday afternoon. The good news is that due to the circulation staying east of the Piney Woods, our impacts will be minimized as the more severe impacts stay off to our east.
Local Impacts Expected
We have flash flood watches that will go into effect early Thursday morning for Sabine, San Augustine, and Shelby counties. With Isaac staying to our east, the heavy rain threat will be confined to our eastern counties and communities.
We have changed our rainfall outlook, which calls for three to five inches along and east of a Center to San Augustine to Hemphill line. Areas along the Highway 59 corridor will more than likely only see an inch or two of rain, with our western counties and communities staying mainly dry.
The other significant impact will be from the winds, which will be ranging from 20 to 25 mph out of the northeast. We may see some gusts over 30 mph, but most wind speeds should remain below tropical storm force. The prolonged winds could combine with the heavy rain in our eastern counties to cause scattered power outages. Based on the storm weakening throughout the day, however, we are not anticipating widespread power outages based on the current track of the storm.
It should be noted that a shift in the track of Isaac by as little as 30 to 50 miles could be the difference as to whether or not you receive several inches of rain or just a half inch. If Isaac drifts more to the east, then rainfall amounts could even be less than what I mentioned above. However, if Isaac decided to take a jog to the west-northwest and move into parts of East Texas, then the rain and wind forecasts would shift further west as well.
