Category 1 Hurricane Carlotta hits Mexico
Posted by: Dr. Jeff Masters, 04:30 PM GMT del 16 Giugno 2012 +28
Hurricane Carlotta made landfall near Escondido, Mexico Friday night at 8 pm PDT as a Category 1 hurricane with 90 mph winds. Carlotta moved inland over the rugged terrain of Mexico this morning, and has weakened to a tropical depression. Since Carlotta was a relatively small hurricane, strong winds affected only a small portion of the coast, and wind damage was probably fairly limited. However, the hurricane has dumped heavy rains along the coast to the east of Acapulco, and two deaths from a landslide triggered by heavy rains occurred this morning in the Oaxaca state community of Pluma Hidalgo. Carlotta will continue to dump heavy rains along the coast to the east of Acapulco, and the 4 - 8 inches of total rainfall that will occur in some areas will be capable of causing more life-threatening flash floods and landslides through the weekend.


Figure 1. Radar image of Carlotta from the Puerto Ánoel radar shortly before the storm made landfall.

The Atlantic is quiet
There are no threat areas to discuss in the Atlantic today. Several models are predicting that a tropical disturbance capable of becoming a tropical depression could form in Mexico's Bay of Campeche sometime June 22 - 24.

Have a great weekend, everyone!

That 10% extra-tropical feature is basically also helping cause training showers across Hispanola. They may have some severe flooding in Haiti over the next few days..... Could be worse than a fast moving tropical storm for those poor folks.

Quoting BahaHurican:
How common is this type of flooding there, pcola? I don't remember hearing a whole lot about this in the past.

I also know that former swamplands [or land along coastal waterways] are prone to flooding in wet wx patterns, and often when housing was built in these areas in the past there wasn't sufficient preparation for this kind of situation. I've seen similar impacts here in Nassau.



Yes there are greedy contractors that develop in hazardous flood areas and sell those tracts to the people who don't do their homework...
And yes flooding has occured like this(1934 is one example)..
But due to the spawl and county burden to maintain areas that were not developed ( too much Federal dollars went into this area because of Hurricaine Ivan...although needed but not regulated properly)
we as tax payers are really maxed out..I own property other than my home..but not for long I'm afraid as I just can't afford it anymore..It was to be for a home for my daughter but she will have to make it the best way she can..she will be OK but so many others won't be..

Seems this type of flooding isn't all that common... so the kind of measures that may have been needed might not have been implemented during the dry years. Unfortunately that is a common story.... and our understanding of these longer term wx pattern is still in the developmental stages even today. :o(

If the overall economy, or even the local economy along the Gulf coast, was stronger, the FEMA help might not be as needed. Maybe some reconsiderations or re-evaluations will be made.

Yeah, we are screwed, I've never seen this much dry weather last this long in June, or in any rainy season month, ever.

JTWC doesn't think so either, the new advisory keeps him at 130kts, though it's forecast to weaken soon. More importantly the new track forecast has shifted west significantly.

We've had our own share of problems with flooding here, especially where heavy rains have resulted in road bed flooding that has caused massive / extensive potholes. Luckily for us the rainfall pattern last month was sporadic enough to keep flooding from becoming more widespread, and we've had a bit of a break in the first part of June. With the MJO headed back our way, though, who knows what may happen...

This is been happening for a few years now. I have seen droughts on the west coast, but not like what has been going on. The backward pattern as we always called it has been more dominant. This certainly is not normal.

Shows more in the big picture. [See 617.] The weakening is more of a decrease in strong winds from the outside.

Crown Weather has always been quite reliable and decent before some of these bloggers were even around here. I would be surprised if Crown Weather plagiarized or copied someones forecast material, but certainly cant rule out that it did not happen. If someone said the Sun will rise tomorrow and ten minutes later I say the exact same thing am I plagiarizing..hhhaaaa !

There is three possible areas where the chance of tropical mischief can occur one is that the low pressure area from the remnants of Carlotta makes its way to the BOC which it spins up and move north especially with the help of the curvature of the coastline in the BOC.

The next one is the moisture in the central caribbean moves in the NW caribb where it meets up with some nice upper ridging that form when the rigde over Panama meets with the one in the eastern gulf thus help it the develop

Finally, the AOI near bermuda becomes the subtropical/tropical development the models have been hinting at early last week. There is a pocket of low shear thats sit almost on top of it so it could develop within the next 48-96 hours the NHC is predicting a 10% chance of development I would put it at 20% within the next 48 hours.
