(Beaumont area, Texas)
"A direct hit from a Category 5 hurricane could cause a storm tide as high as 19 feet above normal along the coastline. Waves would extend an additional 10-15 feet above this catastrophic tide. All coastal communities within 10 miles of the upper Texas coastline would be under seawater ranging in depth from 5 to 30 feet above sea level.
In addition, rivers located within 50 miles east of where the storm made landfall would be filling up to between flood stage and bankfull with salt water and flowing northward, inland, instead of southward toward the Gulf."
