Rare South Atlantic subtropical cyclone forms; severe weather season in U.S. underway

A rare weather event is underway in the South Atlantic Ocean, where the basin's 7th recorded tropical or subtropical cyclone of all-time has formed. An area of disturbed weather (Invest 90Q) off the coast of Brazil, near 30S 48W, attained a well-defined surface circulation, top wind speeds of tropical depression strength (35 mph), a warm core in the bottom portion of the atmosphere, and a cold core aloft last night. If this storm had been in the North Atlantic, there is a good chance it would have been named Subtropical Depression One. However, tropical and subtropical storms are so rare in the South Atlantic that there is no official naming of depressions or storms done. The cyclone had top winds of at least 35 mph as seen on an ASCAT pass at 7:02 am EST this morning (Figure 2), and satellite estimates of the storm's intensity topped out at 40 mph (minimum subtropical storms strength) last night. This morning, the satellite estimates are showing that the system has weakened to a 35 mph tropical depression. There is some moderate wind shear interfering with development, and sea surface temperatures are about 25°C, which is about 1°C below what is typically needed to support a tropical storm. The storm is headed eastward out to sea, and is not a threat to any land areas. The models show the storm will lose its tropical characteristics and get absorbed by a frontal system by Saturday.

Figure 2. Satellite-measured winds from ASCAT clearly show the circulation of the cyclone in this pass from 7:02 am EST on March 10, 2010. Top winds as seen be ASCAT were 30 knots (35 mph), just below the 40 mph needed for it to be a tropical storm. Image credit: NOAA/NESDIS/ORA.

Brazil has had only one landfalling tropical cyclone in its history, Cyclone Catarina of March 2004. Catarina is one of only six known tropical or subtropical cyclones to form in the South Atlantic, and the only one to reach hurricane strength. Tropical cyclones rarely form in the South Atlantic Ocean, due to strong upper-level wind shear, cool water temperatures, and the lack of an initial disturbance to get things spinning (no African waves or Intertropical Convergence Zone exist in the proper locations in the South Atlantic to help spawn tropical storms). Today's storm is located close to where Catarina formed.

Severe weather season begins
It's March, and that means severe weather season will get underway in earnest for the Midwest U.S., and powerful spring storm systems draw warm, moist air from the Gulf of Mexico northward, to collide with cold, dry air from Canada. It's been a quiet early season, with only 42 tornadoes reported thus far this year (as of Sunday), compared to a normal 70 - 100 twisters. There was only one tornado in the U.S. in February, in a San Joaquin Valley oilfield in California two weekends ago. A year ago, there were 36 February tornadoes, and the year's deadliest tornado occurred on Feb. 10, 2009, in Lone Grove, Oklahoma, where eight people died in a storm with winds estimated at 170 mph. But thanks to a very wet winter and a continued active jet stream pattern that will pull strong storms through the Midwestern U.S. this month, expect at least an average March for severe weather. NOAA's Storm Prediction Center is forecasting a "slight" chance of severe weather across a large portion of the Mississippi Valley today, in association with a strong cold front that will be plowing through the region. Strong thuderstorms capable of generating damaging winds and large hail should develop along the front from southeast Kansas through eastern Oklahoma into NE Texas by middle/late afternoon. The storms should consolidate into broken bands and move into Missouri and and Arkansas by early evening. Isolated tornadoes are also possible in the entire "slight" risk area.

Hurricane Hugo talk
I'm presenting a talk to a class at the University of Michigan this morning on my 1989 flight through Hurricane Hugo. You can listen in live starting at about 10:10 - 10:15 am EST by pointing your browser to http://samson.lecturetools.org/. You'll need to have Apple Quicktime installed. If all goes well, the talk will be recorded and you can view it later, as well.

From the warning reports. I'll post in a few. Tornado outbreak is underway.

I haven't seen a nado warning that goes beyond the usual doppler radar indicated with a "could be".

Show us, please?

No it's not, but few people make the effort to figure it out. If the code behaved properly, everyone would be using it, but they don't, because unless you're told how, you have to play around for a while to figure it out, and not many people are willing to do that for the sake of a few colored words. That is fortunate, or as you said, things would get crazy.

Tropical storm with 40 knots in Costa gaúcha The world map of tropical cyclones disclosed in real-time by NASA, the u.s. Space Agency, showed two tropical storms in the southern hemisphere, Hubert in Madagascar in the Indian Ocean, and the nameless cyclone in the Atlantic coast of Rio Grande do Sul.



The symbol that you on the map and accompanies the title of this analysis is used in the identification of tropical storms, but with the reverse movement to hemispheres of cyclones. When a hurricane, the icon is the same, but with the Fund completed. The tropical storm that is on the coast gaúcha follows your offset to the East, away from the continent, but gained strength in the last 12 hours.

The wind maximum continuous its Center passed to 40 knots, only 25 us unless necessary for the characterization of a hurricane, and it would be only the second documented throughout the history of the South Atlantic, which signals the as is extraordinary and rare this weather system, despite it not having passed very in continental area. The indicative that he will have some dificuldaded on achieving the rank of hurricane on the high seas, which could discard, but it is vital to stress, that we have never been so close to register a new Catherine and the luck, if you believe it weighed. Best track data of LARGEST/TPC/NOAA indicate that the maximum that the system has reached so far in Dvorak scale was 2.5, i.e. below 4.0 compatible with a hurricane.

The impressive, and I would say so sad, is that there are even climatologists-none here in southern Brazil-making where one tropical storm in Brazil. Were the same phenomenon this now in the North Atlantic and he would get the first name of the list is designed for 2010 that would be Alex. Perhaps nobody has attempted to detail, but our cyclone is the first tropical cyclone and the first tropical storm of the year in the Atlantic Ocean, something exceptionally rare, since virtually every year the first Atlantic tropical cyclone in the northern hemisphere. A tropical storm is taken so seriously in the United States State authorities often suggest evacuation of coastal areas when approximating a system of this kind, as shows Fox News story below 4 September 2008, when the tropical storm Hanna of South Carolina.

I know effects can be quite annoying and I'm using mine wisely. "Tornado Warning" were the only two words I made blink in red in the warning message.

NINO-West (the region in the west Pacific just east of the Philippines and north of New Guinea) is forecast to trend warmer than normal as we head into hurricane season. This would be consistent with a dying El Nino and the beginnings of a La Nina in the east-central Pacific.

The tornado outbreak is now beginning and looks like it is going to be a long evening as numerous tornadoes may touch down between now and midnight.


I have a feeling strong storms are going to fire all night long ahead of this front and won't quit at midnight. Strong storms rolled thru my area at 3:30 this morning from the warm air out ahead of this front so I have no doubt it's going to be another long night as the front gets closer. My 2 year old loves thunder and lightning, he thinks it's just another cool fireworks show so he should enjoy tonight!

New MetEd/COMET tropical module

The COMET Program is pleased to announce the publication of "Chapter 11, Observation, Analysis, and Prediction of Tropical Weather", of the online textbook, "Introduction to Tropical Meteorology". This textbook is being developed over time and its chapters are being published incrementally. This is the fifth chapter in the book to be published. It includes a focus section on the Australian-Indonesian Monsoon contributed by Dr. Mick Pope of the Australian Bureau of Meteorology. Other special features are interviews with tropical cyclone forecasters from the U.S. National Hurricane Center and Tropical Cyclone Centre Météo-France/La Réunion. Please follow this link to open the textbook: http://www.meted.ucar.edu/tropical/textbook/index.htm. The chapter covers methods of tropical weather observation, analysis, and prediction. Learners will become familiar with:

- The challenges of tropical weather analysis and forecasting
- Advantages and weaknesses of various types of tropical weather observations and sources of observation error
- Tropical weather analysis using tools such as streamline/isotachs and velocity potential to analyze station data and satellite products such as IR anomalies, cloud drift winds, total precipitable water, and more
- Mesoscale analysis and nowcasting using high-resolution satellite images and radar imagery
- Marine analysis tools and marine forecast products commonly used in the tropics
- Numerical weather prediction in the tropics including advantages, weaknesses, and data assimilation techniques, and forecast verification methods.
- Applications of dynamical, statistical models, statistical-dynamical models
- Ensemble prediction systems, some applications in tropical weather, interpretation and verification of ensemble products
- Tropical cyclone prediction including the advantages and weakness of model guidance
- Different types of monsoon regimes and weather systems common to each intraseasonal period
- Seasonal and intraseasonal rainfall variability over Australia and Indonesia including the impact of prevailing winds and topography on the evolution of convection.

The chapter uses a variety of strategies, from graphics and animations, to critical thought questions and interactions, review questions, and a quiz. Each section has links to additional sites and resources that augment the material presented in the chapter. The material has been reviewed for scientific accuracy and academic level appropriateness by scientists and a professor with expertise in tropical meteorology and diverse regional perspectives. This chapter includes graphics and a companion print version in PDF format. The intended audience for the online tropical meteorology textbook comprises undergraduate and early graduate meteorology students, current operational or prospective tropical forecasters, and students interested in tropical meteorology.

Some bloggers this year, including myself, are using kewl HTML code to make warnings stand out, since internet browser code development has been getting pretty creative over the last few years. If you are using Internet Explorer, it may not be pretty at times as IE has major problems displaying webpages with these kinds of codes, so sometimes an entire comment may get affected when we only coded one word. If that happens to you we are sorry, but other browsers like Firefox and Chrome do not have that problem.

Tropical Disturbance Advisory Number SEVEN
FORTE TEMPETE TROPICALE HUBERT (13-20092010)
22:00 PM Réunion March 10 2010
====================================

At 18:00 PM UTC, Severe Tropical Storm Hubert (987 hPa) located at 21.1S 48.7E has 10 minute sustained winds of 55 knots with gusts of 80 knots. The storm is reported as moving west southwest at 5 knots.

Dvorak Intensity: T4.0

Storm Force Winds
=================
20 NM from the center

Gale-Force Winds
=================
35 NM from the center extending up to 45 NM in the southern quadrant

Near Gale-Force Winds
=====================
40 NM from the center extending up to 45 NM in southwest and north and 55 NM in the southeast quadrant

Forecast and Intensity
=====================
12 HRS: 21.4S 47.4E - (Depression sur terre)
24 HRS: 21.5S 46.0E - (Depression sur terre)

Additional Information
=======================
Hubert has rapidly intensified as it approaches Malagasy eastern coast. System is located at less than 30 kms of Mananjary City. Latest visible image show an improving curved band pattern with convection wrapping more than 10 around low level circulation center. 1608z SSMIS imagery shows an eye feature on 91 ghz channel with improving organization compared to previous microwave imagery from AQUA and TRMM.

On this basis, FT is upgraded to T4.0 for this advisory (Dvorak constraint at +0.5 in 6 hours or FT broken due to rapid intensification for a small system).

MSLP remains adjusted higher than normal to take into account the high environmental pressure (set at 1013 hPa). Landfall is expected within the next hours near Mananjary as system is currently slowly moving towards the west southwest. After landfall rapid dissipation is forecast over the high terrains of Malagasy.

Wow thats insane. Wish I could see that much snow I've never really been on that much snow. When we were up in Alaska I could see it but never went to it. Down in Houston we don't get much snow so I'm hoping to see that much sometime. Although we do get a lot lightning which you haven't seen.


Indeed, there are a lot of things you guys get that I have never seen lol. All we have up here is snow...that's it...nothing else exciting exists here.

Well the models don't seem to think the IOD will be too significant this year. By the looks of the model it may be trending slightly positive over the course of the summer, but the entire Indian Ocean is just flat warmer than normal right now.

Umm, wow.


Yeah! Here's the short synopsis I wrote on the last page before CyberTeddy posted that notification. I was hoping the convection would be deep enough and it is :)

Last visible shot before sunset on Invest 90Q. There is some very nice deep convection partially covering the LLC, the deepest convection we have seen yet with this system. There is also an impressive spiral band in the eastern semicircle. West to northwesterly wind shear is preventing the system from strengthening much, and is responsible for the LLC being partially exposed. However, this is the best and most tropical I have seen this system look so far.

90Q has begun to move eastward over the last 12 hours in response to a deepening trough digging in from the southwest. The system will continue eastward over the south Atlantic and gradually curve poleward towards the southeast over the next couple days. Today is likely the last day before 90Q undergoes extratropical transition.

In commenting late about Alaska storms, the Anchorage airport shutdown about 6 yrs ago in the winter due to some strong winds from the north. Winds on the "hillside" above Anchorage were clocked in excess of 90 mph. Funny thing is, it wasn't the winds that shut the airport down, it was the flying debris becoming a hazard.

For anyone that has had the priviledge to fly into that airport with the interesting winds generated off the Turnagain and Knik Arms. I have had way to many white knuckled landings in my time there.
