Tropical Depression Two Along South Texas Coast

Hello everybody, this is Senior Meteorologist Shaun Tanner writing Dr. Masters' blog while he is on vacation.

Tropical Depression Two formed overnight in the northern Bay of Campeche and is now making landfall along the extreme south coast of Texas. A hurricane hunter was sent into the system and found a low-level circulation. While there are some reports of tropical storm strength winds in the squalls of the system, there is just not enough evidence to upgrade the storm to tropical storm strength before landfall.

The satellite representation of the depression is quite impressive as half of the depression is now over landfall. Brownsville radar currently is showing the effects of the depression with heavy rain and thunderstorms through much of southern Texas.

The biggest lingering effect from the depression will be to prolong the devastating flooding that has been ongoing in southern Texas and northeast Mexico. Not including the rain that will fall due to the depression, over the past 7 days, the area near Houston has received over 10 inches of rain, while some inland areas of Texas has received over 4 inches of rain. The problem gets worse in the Mexican state of Coahuila near the Texas border has received upwards of 20 inches of rain in the past 7 days due to substantial moisture pouring into the area.

This surging watershed has caused massive flooding throughout the region, with the area near Laredo, Texas and Nuevo Laredo, Mexico being the hardest hit. The flooding has caused the major border crossing between those two cities to be closed as the Rio Grande surged and threatened to top the crossing's bridge. A contingent of Mexican officials, including the mayor of Piedras Negras, Coahuila, touring the flooding damage in an airplane crashed Wednesday, killing all six onboard. Evacuations on both sides of the border has forced tens of thousands of people out of their homes, while over 100,000 people were without water service. The flooding problem is extra dangerous because swollen dams had to release some of their water downstream into areas that towns that have already been swamped. It was even reported that one of these releases by the National Water Commission of Mexico was the largest emergency water release in the country.

Needless to say, the rain from Tropical Depression Two will only further the flooding problems in southern Texas and northeast Mexico. Figure 3 shows the severe map and the greens represent Flood Watches and Warnings. You can see almost the entire states of Texas and Oklahoma are under these watches and warnings in anticipation of several inches of rain from the remnants of Tropical Depression Two.

I don't think joking about a Cat 5 hitting a major metropolitan area is funny.


Oh come on...... grow a sense of humor! LOL
Not like I meant any harm or malice to anybody...... except the same politicians that won't fund a decent wind satellite!

I refuse to be a stoned face robot in this blog..... especially when there is little actual discussion going on!

StSimons...... you been around for years...... you know I like to have a little fun when I can! :) Heck, I haven't been banned in almost a year! LOL

Yep, Saw some blue sky this afternoon. Feel for the flooded peeps down south in Brownsville. That Rio G is big time swollen.
Maybe this will be the extent of trop weather
for the western Gulf this season. LOL

I'm in SE Houston, Pearland. We went for a nice bike ride after supper. We hit a few puddles, but it was great to be out!


Richmond area here but relocating to the League City area...this rain has put some jobs on hold so looking forward to the improvement. Glad you guys in Pearland are beginning to dry out too.

wrong, LeBron will hurt Bosh and Wade I think; too many egos

Magic will win the east anyway, Miami would have been better off with just Bosh and Wade

ok back to the tropics lol

Just what we need..... a Cat-4 to wipe out NYC!

Any way we can get a Cat-5 to DC? LOL


You're going to need something more than a cat 5 to do the trick. Congress alone generates enough wind to keep just about everything out.

Looks like it may be very slowly coming together...would love to see a temperature profile on it...see if it's starting to transition.


Well, 18z GFS and UKMET say it's getting close to shallow warm-core but not quite there yet.

OK Storm, make me ask! Thoughts on the Disturbance on the outer banks? Seems it only has 36-48hrs, and will be moving out.....

Definitely an interesting feature........

Saw the sun shine tonight for the first time in a couple days. I'm glad for a pause in the tropics for now. I'm in the Houston area and though we have not been directly hit by a storm, the rain has been enough! This is currently the 8th wettest July on record and it's July 8th!

And yet, despite the stronger-than-normal high, surface pressures south of 20N remain 1-2mb below normal in that image.
Very interesting.

I agree with you on this Ike. Someone can tell me I am wrong on something and well I might be but if you can't show me how I have no reason to believe I am.

Gosh. My starting point is that I am wrong. Seek first to understand and then to be understood, I always say.

The 12z UKMET shows the subtropical ridge (B/A high) with a pressure of 1035mb. That's pretty impressive if ya' ask me.

120 hours.
