Tropical Storm Hanna Update
Status Update from the Office of Homeland Security and Emergency Management

MONTGOMERY COUNTY –Tropical Storm Hanna has continued to strengthen with wind speeds of up to 45 MPH, and has shifted more to the south. A tropical storm warning has been issued for much of the southern Texas coast from San Luis Pass southward, and the tropical storm watch which had been issued from San Luis Pass to High Island has been dropped. Strengthening is expected over the next few days as it tracks across the warm waters of the Gulf towards the Texas coast.

Tropical Storm Hanna is expected to produce heavy rains across portions of Louisiana and Southeast Texas, which could result in flash flooding. This storm is expected to produce between 1 to 2 inches of rain with isolated maximum totals of 4 inches along the Gulf coast. Locally higher amounts are possible in any heavier rain bands. Our heaviest rains for the area are expected to be Friday night into Saturday, and we are at a marginal risk for flash flooding starting Friday into the weekend. The confidence on the track of the storm is increasing, but there is still considerable uncertainty on the amount of rainfall from any banding that could set up on the right side of this storms track.

Additionally, our office is monitoring Tropical Storm Gonzalo which has formed over the Atlantic, and continues to strengthen. Gonzalo is expected to move near or over the southern Windward Islands this weekend. Hurricane Watches are currently in effect for Barbados, St. Vincent and the Grenadines, with additional watches for other islands be announced later today. We are continuing to keep a close watch on Gonzalo as the storm track develops and makes its way West. It is important that residents of Montgomery County begin to prepare and keep a close watch on these storms in the Gulf. Next update expected to be at 5PM.
