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've had 2.92 inches of rain in July.

I nominate Leah as a name for the "L" storm in the Atlantic.
I nominate Robert (my name) as the "R" storm. Interesting fact, did you know that the name Robert has never been used to name a system?

2004 was just a bad year in general.Not only did florida get blasted,but due to tropical rains it brought floods all throughout the southeast of the untited states.Here in baltimore I remember getting the remnates of a few storms.We had some heavy downpours which caused street flooding in some cases.I still think to this day that the 2004 hurricane season took some people by surprise,due to it's late start.
I remember Charlie like yesterday... I was taking some precautions and had plywood already for some windows... I started to put up some of the wood before it crossed over cuba... then the rapid intensification began.. I started the wood to a (I believe a cat 1) and finished it was a cat 4. We live on top of a very high hill for Florida 160' above sea level so we got the full force winds. The rest of the season we lived with my parents since they have a large well built house. What a crazy year that was.

LOL me too.. I lived through a few in my time as well and would rather live around them as well! Here in Florida we pretty much cant avoid them here on the sandbar but a drive up or down the coast can get us to safety. Sure didnt feel that safe in 2004.. I have to admit if I had to spend one more minute with the ones I love in a tight confined space I thought I would need some therapy.


Lol. I know whatcha mean. After Rita it took 4 generations of my family a week to finally end up in the same place. Afterwards my parents had 1 family in each of their bedrooms. My 3 piece were the last to leave after 9 MONTHS! Amazing they still speak to us. :)

I nominate Spooky as a name for an "S" storm in the ATL...ARS version.......

83.7 outside...humid....dry in the NW Florida panhandle.....


Looks like the heat's building back into the Gulf Coast states after a prolonged period of heavy rainfall. Supposed to be in the mid 90s here everyday for the next week, with lows in the mid to upper 70s.

Certainly not good for the water temperatures, but this ridging pattern is favorable for fair weather.

Oh well. I'm not very politically correct. Always been like this. I don't know about being scientific but I am interested in these storms. There's nothing you can do to stop them. I'm a big fan of getting out of their way. I guess I'm just destined to love them from afar. :)

I know I'm not the most humble person....I'll argue to the death if I think I'm right. That can give me a rather less than attractive personality, and for that, to all on the blog, I apologize.


It's no big deal, at least for me. Still, I can certainly understand why you get under the skin of some people here. I think sometimes you need to be a little more tactful. Just some advice. Don't think I'm trying to lecture you though.

I'm much the same way, which is why I'm trying to help you here, Levi. But I've had to learn to tone myself down a bit. You can argue till hell freezes over, just make sure you do so in a way that doesn't paint you as condescending or arrogant.

I am taken aback by this statement. I see this sort of stuff happen all the time. Intelligent people treat PUBLIC issues as separate from PRIVATE issues. Unfortunately there are those who launch personal attacks because they cannot handle their ideas on public issues being challenged. Your earlier comment on how one learns most through debate and challenge is correct. People should thrive on debate and derive pleasure from having their ideas being criticized. Those who cannot handle the heat in the kitchen have super inflated egos, preferring automatic validation without putting the hard work people like you do to earn your elevated knowledge.

I don't know how he read it. My point is not necessarily about the conditions in the mid-levels needed for tropical cyclogenesis but about the cyclogenesis itself....it doesn't occur just down at the bottom in the surface layer. It occurs in both the low and mid-levels at the same time, though the system is of course strongest at the surface.

I guess...the upper levels is more important than the mid levels during true cyclogensis. All about convergence at the surface and divergence aloft to be the exhaust pipe. I have see very unfavorable mid level systems form that typically are dry but can still pack a huge punch with winds at the surface due to strong convergence and a great upper level environment.

This is what starts political correctness and keeps people from communicating. I personally think you comment is out of order in the sense that you knew and know what he meant. Ill bet not one person took offense and knew he meant it from a scientific perspective. It is sensitive but I have seen people on this blog beg for storms to form.. That is what the scientist part of all of use are here for. The humanitarian side doesnt want any one to lose their home or life for that matter.

IMHO

Miami,
PLEASE take your little red arrows and circles and point them in another direction! Any more rain here and my dogs will have to swim to use the restroom....
PSU e-WALL forecasted steering stays that way through 168 hours. So if anything forms in the Caribbean, it will likely do a track similar to what I depicted.

This is unbelievable, again the Santa Catarina river in Monterrey is raising rapidly and the threat of cresting is very likely or inminent. Some spots during the last 7 days already have received over 1 meter of rainfall.

yup no question, but of course the questions will continue

Yea, I guess the only question would be is it a one time gust? an outflow from a collapse TS? or were the winds for over 30 ot 60 minutes pushing close to that 36mph value? If it was a one time thing and winds were consistently around 25mph then I guess questions are fair. I am good with it being a TD but it was far from a TS so glad they didnt upgrade.
