Hurricane Harvey has reformed over the Gulf of Mexico after previously dissipating as a tropical depression. Harvey is in a location that is currently very favorable for rapid hurricane intensification: low wind shear and warm ocean waters. Right now, on the current forecast track, Harvey is expected to make landfall along the Texas coastline late Friday night or early Saturday morning. Harvey may make landfall as a Category 2 or Category 3 hurricane.
The latest details as of 5:00 pm EDT Thursday, 8/24/17:
- Location: 305 miles Southeast of Corpus Christi, TX or about 300 miles South Southeast of Port O’Connor, TX
- Maximum Sustained Winds: 85 MPH
- Movement: North Northwest at 10 MPH
- Minimum Central Pressure: 976 mb (28.82” Hg)
Harvey is expected to intensify rapidly over the next 24 hours and may become a major hurricane prior to landfall (Category 3 or stronger). If it does, it could be the first major hurricane to make landfall in the United States in over 10 years. Along with very strong winds, very heavy rainfall is expected with Harvey, with some locations forecast to receive 15+ inches of rainfall over the next few days. Additionally, storm surge flooding could exceed 9 feet in many locations along the Texas coastline.
Once Harvey moves inland, a gradual decrease in both intensity and forward speed is expected. Harvey may stall out over southeastern Texas through the weekend and early next week. This will exaggerate flooding as very heavy rainfall will continue. A storm total rainfall forecast of 15-25 inches of rain is possible through next Wednesday, with some locations possibly receiving 35 inches of rain.
Here’s the latest storm surge forecast from the National Hurricane Center:
- N Entrance Padre Island Natl Seashore to Sargent…6 to 12 ft
- Sargent to Jamaica Beach…5 to 8 ft
- Port Mansfield to N Entrance Padre Island Natl Seashore…5 to 7 ft
- Jamaica Beach to High Island…2 to 4 ft
