I smell a PTC coming I may be under a tropical storm warning soon here in Galveston lol absolutely beautiful day today

Recent satellite wind data indicate that a broad low pressure area
has formed in association with the tropical wave over the central
Gulf of Mexico. However, the accompanying shower and thunderstorm
activity is currently poorly organized. Conditions appear conducive
for additional development, and a tropical depression is likely to
form during the next day or two as the system moves west-
northwestward at about 10 mph. Interests in the western Gulf of
Mexico should monitor the progress of this system, as watches or
warnings could be required for portions of the coasts of Texas and
Louisiana later today or tonight. An Air Force Reserve Hurricane
Hunter aircraft is scheduled to investigate the system this
afternoon.

* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

This looks promising for Tropical Storm Warnings soon. I hope it can trigger some inland storms once it goes around the ridge.

Data from the Air Force Hurricane Hunters and surface observations
indicate that an area of low pressure over the central Gulf of
Mexico is gradually becoming better defined. However, the
accompanying shower and thunderstorm activity is still poorly
organized. Environmental conditions appear conducive for slow
development of this system, and a tropical depression is likely to
form during the next day or so as it moves west-northwestward at
about 10 mph. Interests in the western Gulf of Mexico should
monitor the progress of this system, as watches or warnings could be
required for portions of the coasts of Texas and Louisiana tonight
or on Thursday.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

Area of subsidence between the LLC of TD8, and the lower pressures closer to the mid-level vorticity that are seemingly spiraling towards each other, sort of looks like an eye feature. I've seen this with other storms when vorticities begin to stack up. Once that happens, environmental conditions look almost perfect for rapid intensification. I can imagine a scenario where Hurricane Hunters fail to find tropical storm force winds tonight, and this develops into Hurricane Hanna by tomorrow morning or early afternoon.

This could be an exciting 48 hours. In regards to development of waves into cyclones, these are the types of storms and situations that ignite my passion in meteorology.
