HOUSTON — The KHOU 11 Weather Team continues to monitor the tropical disturbance in the Gulf of Mexico.

In its 10 a.m. update The National Hurricane Center just upgraded the system to Tropical Storm Barry, but it will likely strengthen to a Cat. 1 hurricane by the time it makes landfall.

10 a.m. Thursday Advisory:

A Hurricane Watch has been issued for nearly all of the Louisiana coastline, and a Tropical Storm Warning has been issued new New Orleans. Max sustained winds are 40 mph with the system moving west at 5 mph.

New Information:

  •  A second hurricane hunter has just completed a pass through the system
  • At this time there are no watches or warnings anywhere along the Texas coast although portions of the coast near New Orleans are now under a Tropical Storm Warning and a Storm Surge Watch.

What We Know:

  • NHC has increased the probability of development to 100%
  • The disturbance moved into the Gulf of Mexico
  • Hurricane recon plane is in the air
  • We should have a better forecast track Thursday morning
  • It’s important to understand the uncertainty – the models could shift back to Texas just as easily as they shifted to Louisiana
  • If Houston ends up on the western side of the system, we will be on the “dry side” if Houston ends up with a direct hit or on the eastern side of the system, we will be on the “wet side” and can expect more rain and wind.
  • Continue to review your hurricane supplies and become familiar with what evacuation zone you’re in and what route you’ll take in the event one is called.


Where the storm ends up and how close it gets to the Texas coast will have huge implications on our forecast for the weekend. 

If the center of the storm stays to the east of Houston, we could end up with a hot dry weekend. 

A shift to the west and closer to Houston would be more likely to bring more wind and rain. That’s why getting data back from Wednesday’s Hurricane Hunter flight is so important.

Everybody wants to know how strong this storm could be and the answer is that all possibilities exist from a weak tropical storm to a strong hurricane. The gulf is ripe for development with water temps in the upper 80s and a very low wind-shear environment. 

What we don’t know:

  • We don’t know how strong this system could be. All categories are on the table.

What do you need to do?

  • Make sure you check on the weather at least twice a day; once in the morning and once in the evening.
  • Check your hurricane supply kits. Make sure you’re ready in the event we get a storm, which at this time remains very uncertain.
  • Go over your storm plan with your family. Where would you go? What route would you take if asked to evacuate?
  • Stay informed. Check in with us twice a day. Once in the morning and once before you go to bed so you don’t get caught off guard.



What are high pressure cells?

Steering currents will be the drivers for the forecast come Friday and Saturday here locally.

Think of high pressure cells as bumpers. Hurricanes, as ferocious as they are, are lazy and don’t put up a fight with high pressure. They just go as they are told so-to-speak. As long as a high is over you, you’re good. The area of high pressure that was centered over us is backing westward and that will allow a small opening for a big moisture source.
