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.

Nah, looks like the GFS is just developing spurious areas of low pressure again... Which means it must be discounted from the forecast.

It was not as bad as it could have been, Jedkins---the west winds mixed down drier air from above and the dewpoint was 65 at peak temps today. 101 with a dewpoint of 65 is 31% humidity, and the heat index was 105.

Back on our hottest day in 1986, it was 104, with a dewpoint of 72. The heat index was 115.

Have seen higher heat indexes than that when we have had a seabreeze raise dewpoints to 81/82, with the temperature 93/96. Then the heat index has reached 120---highest I can remember is 122.



Yeah usually on the hottest days the dry air does mix down... But every now on then you get the worst combination between muggy air from the seabreeze but yet never really cooled off by it...

We had several days with the heat index was around 110 to 120 last month. It got that bad in June last year too!

It seems June is the hottest month around here in the summer. We just get too much rain around here the rest of the summer months. Like now, we had so much rain last 2 weeks, that this hot dry spell last few days isn't turning out that bad. The ground has been rain cooled excessively, to where the sun seems to focus more on moisture evaporation rather then rising the air temperature.

Jedkins, yeah we get 100s about 1 out of 3 summers, and usually more than one day when we do have them.

It is hard to get to 100 here, because the seabreeze usually kicks in when it is that hot. The seabreeze actually did kick in today--we had the temp fall from 101 to 91 between 4:30 and 6:30, then the seabreeze failed and the temp warmed back up to 94 by 8:15 before falling again.

I do think this night will stay above 80, however.

Link

The west wind is stronger tonight. It will be interesting to see if storms form and keep us from getting to 100 again. Or if we really soar up to 102+.



Man that is crazy! That's usually what keeps us cooler too as the sea breeze, there were a few days back in june I thought we might just top 100, but the sea breeze held us steady every time between 97 and 99! In fact my weather station several times came ONE TENTH of a degree from 100 but never quite got there! lol

Over the 7 years Ive had a weather station, its never hit 100 at my house. I'm thankful to live by the coast in central Florida!

Honestly though, no matter what the numbers say, chances are it still feels hotter in Florida, whether it be the sun's intensity or the deep tropical moisture always floating in the deep tropical moisture around as well as all the swamps and wet lands.

But you're in southern Giorgia, which won't be very different from Florida, so I can imagine 101 is a huge deal there too, it must be really oppressive!

hahaha its probably because I'm in college these days, whereas before I was a high schooler with way too much extra time. Even being an outdoor boy with a lot of good friends, I still always had way too much extra time to blab about weather on here.


I actually do check in here very often, I'm just usually not on the computer for more than 10 minutes or so lol.

I remember you though! I wonder how many originals are left? I was on here the first year Weather Underground created blogs! I'm an old timer around here, I even got banned a couple months ago for getting a little too upset at one of those angry bloggers like centex! lol

I guess being a blog old timer must be like being an old timer in real life, you think because your old you can say whatever the heck you want as long as its for a just cause! lol


haha! Yeah, high school allowed me to be on here more frequently, college is eating my time too. XD
Yet I somehow manage to log in everyday and check this blog, take pictures to keep my Wuphotos active while checking my Facebook O.o and then to study, I guess I'll go mad eventually. LOL
But I'm not that old on here LOL just three short years. XD

Jedkins I like centex, and I've seen much, much worse. LOL.

We got to 101 today. Hottest since 1998.


hahaha well Ive been on here a while, I guess I thankfully miss the worst of the worst then! lol


at any rate, wow 101? That's pretty bad! We had a lot of 98's and 99's last month in june, but never quite 100, that's a really hard number to achieve along the Florida west coast.

Last couple days have felt like spring, highs around 90 and dewpoints got as low as 65 with afternoon mixing due to very dry air mass aloft.


Man after having over 9 inches of rain in just 1 week. We are now in a disturbingly dry air mass. The PWAT reached as low as 1.03 at Tampa yesterday which is just horrible!

This is like last year, we just don't get the daily thunderstorms like we used to, we get a deep trough that soaks us for a while, then a deep high follows and dries us out a while.


Its starting to get more mid-latitude like in Florida, the winters have gotten colder, the summers have gotten hotter, and the winter and spring have gotten wetter, and the summer and fall have gotten a little drier. There seems to be less distinguishing between wet and dry seasons, and more extreme winter lows and more extreme summer highs...

Hopefully this is isn't a long term trend, I don't like mid-latitude climates at all, I like the tropics.-

Go watch my video from that day lol. You're completely mis-interpreting it.

Heck here it is:





A couple of things I missed that day were that only a portion of that surface circulation would make it to NE Texas/SW LA and the southern part hung back over the area of greatest pressure falls, which did allow the system to eventually get vertically stacked with part of the old surface circulation, which reformed into a new one that became the closed surface low.

Jealousy is a common theme in this blog, happens every year. I'd rather have the respected bloggers be people who have actually set foot on a college campus since this is a highly complex field of study but it is what it is. They do a good job regardless and in the end that's what matters.

Then again, I wouldn't know what a good analysis looks like since this isn't my field. Nothing wrong with pointing out "mistakes" or contending certain points but leave the personal attacks out of it.
