The Tropics are quiet as of now and here is what is going on down there. If you click on the picture, you can see a bigger view of this graphic. There is a swirling upper level low pressure in the Western Gulf of Mexico moving towards the west. Now this is an upper level low pressure and not a surface base low near the ground or ocean. We do not worry so much about Upper level systems because this system is a high atmosphere weather situation and is not favorable to produce a tropical system. For a tropical system to develop, we need a low level low pressure system that is surface based. A surface
low basically. To the right is a closer visible satellite picture of the Unsettled weather in the Western Gulf. This will bring some much needed showers to Northern Mexico and Deep South Texs over the weekend. In the Caribbean, I highlight where there are some streaky clouds do to fast high level winds way up in the atmosphere. This is also an area of non favorable conditions because for tropical systems to form, we need light winds and no shear, with over all quiet weather around the surface low. And looking at the latest satellite picture and conditions, I don't see anything to be concerned about now or in the near future. Models do no show anything in the tropics for the next 7 to 10 days as of right now.
This is a special satellite picture called QuickSat which allows us to see wind direction and wind speeds from a satellite over the oceans and this is a handy tool when we don't have very many weather observations over the water areas. This also confirms that there is no low level low pressure center in the Gulf where the unsettled weather is.I hope you enjoyed today's Tropical Update on my blog. This weekend I will be putting together some maps closer to home here in Central Texas of the developing Drought conditions that we are experiencing. So check back in on my weather blog and make sure you catch me on NBC 6 News with your weekend forecast and more about the Drought here in Texas on Saturday 6pm and 10 pm and Sunday 5 pm and 10 pm.
Take Care!

Thats good news about the tropics. I am afraid of what gas prices will be like when a hurricane gets in the Gulf. Could you imagine 7 or 8 dollars a gallon?
Yeah I agree with you about the gas and a hurricane in the Gulf. I think the whole country would be crippled with a gas shortage from something like that. Get your walking shoes ready!
