Thursday Morning Update

Harvey strengthening

The Weather Situation
Harvey is organizing quickly and I would not be surprised if it is a hurricane by early this afternoon. Outflow aloft appears strong and deep convection has wrapped around the center. Harvey will pose a serious flooding threat to SE Texas with widespread 10-15" amounts with much more possible. Now is the time to prepare and plan. Storm surge and wind damage will also be a concern, especially near and north of landfall which is predicted to be near the central Texas coast.

Current Tropical Weather
As of 7:00 AM CDT Tropical Storm Harvey was centered at 23.8 N / 93.0 W or 335 miles SE of Port Mansfield, Texas. It was moving NNW at 10 mph. Top sustained winds are estimated at 60 mph. Pressure was estimated at 986 MB.

Tropical Weather Forecast:
Harvey will continue NW toward the Texas coast and is predicted to strengthen before reaching the coast. It will then stall with weak steering currents. Because of this, flooding rainfall is a major concern. By early next week Harvey will start to move east / ENE into Louisiana. Landfall is predicted to by Friday night.

The Weather Situation

Tropical Weather Forecast:
Harvey will continue NW toward the Texas coast and is predicted to continue to strengthen before reaching the coast. It will then stall with weak steering currents. Because of this, flooding rainfall is a major concern. By early next week Harvey will start to move east / ENE into Louisiana. Landfall is predicted to by Friday night.

Friday Morning Update

Harvey a dangerous hurricane

The Weather Situation
Harvey has strengthened significantly over night and will make landfall on the central Texas coast tonight. All preparations should be rushed to completion this morning. Hazards include, storm surge where the eye comes onshore and north of that location, devastating flooding with up to 30"+ possible, wind damage and isolated tornadoes.

Current Tropical Weather
As of 7:00 AM CDT Hurricane Harvey was centered at 26.3 N / 95.8 W or 140 miles SE of Corpus Christi, Texas. It was moving NW at 10 mph. Top sustained winds are estimated at 110 mph. Pressure was estimated at 950 MB.

Saturday Morning Update

Harvey inland, bringing heavy rainfall

The Weather Situation
Harvey has moved inland officially at 10 PM CDT and its legacy for bringing flooding rainfall is well under way with up to 10" measure so far. At this point the top gust was at Aransas Pass with winds to 102 mph / gusting to 132 mph. This is well below the supposed category 4 strength of 130 mph. Sustained winds of 130 mph and gusts to 150 should have been measured. The hurricane hunters measure stronger winds aloft, but many times winds will not translate all the way to the surface. It will be interesting to see if any sustained winds to 130 at found in post analysis.

The highest water above mean water level was at Port Lavaca on the central coast at 6.4 feet.


Current Tropical Weather
As of 7:00 AM CDT Hurricane Harvey was centered at 28.7 N / 97.2 W or 20 miles WSW of Victoria, Texas. It was moving NNW at 6 mph. Top sustained winds are estimated at 80 mph. Pressure was estimated at 975 MB.

Tropical Weather Forecast:
Harvey is slowing moving inland. It will drift south again to near the coast by Monday night and eventually move NE into eastern Texas as it weakens. Harvey's strength will depend if it actually drifts back over the Gulf of Mexico Monday where it could restrengthen.
