UPDATE:   19 Aug. 2007
Currently, it looks like Dean will make Cat. 5 and fall far south of Texas. People in the Yucatan Peninsula as well as central and coastal Mexico need to be on high alert and evacuate if possible or at least secure shelter and enough supplies to survive for a week or more.
Although it could make a sharp turn after it hits Cancun and come across the Gulf (and regain strength), it's somewhat unlikely. However, we're not clear until it hits the Mexican mainland.
Hurricane Dean is predicted to make landfall anywhere from Brownsville (about 450 miles from Beaumont) to southern Mexico. It's a major storm and requires attention. It's best to prepare now.
The Beaumont Enterprise has developed Texas Hurricane News. It's a comprehensive site with checklists, evacuation maps, hurricane tracking maps, post-storm advice and other features. It contains useful advice for anyone living along the Gulf or East coasts.
Additionally, there is an online forum to locate separated family members or exchange other hurricane-related information.
It was developed after hurricanes Rita and Katrina and incorporates lessons learned.
Enough for now,
