Giovanna hits Madagascar; major damage likely
Tropical Cyclone Giovanna powered ashore along the east coast of Madagascar as a destructive Category 3 storm with 125 - 130 mph winds at 22 UTC last night. Winds at the coastal city of Tamatave, 70 miles north-northeast of where the center came ashore, peaked at 52 mph, gusting to 71 mph. Giovanna is moving west across the island at 17 mph, and passed just south of the capital of Antananarivo as a Category 1 storm at 8 am local time Tuesday morning. The eyewall missed Antananarivo , and the peak winds in the city were 38 mph, gusting to 55 mph. Microwave satellite imagery from the Navy Research Lab in Monterrey showed that Giovanna had rainfall rates of up to one inch per hour at landfall, and it is likely that the storm dumped 5 - 10 inches of rain along much of its path. The heaviest rains fell on deforested mountain slopes that drain into some of the most densely populated regions on the island, so major flood damage is likely. Heavy wind and storm surge damage undoubtedly occurred where the core of the storm hit the island, as well.

Seven hours previous to this time, Giovanna was a Category 2 storm with 110 mph winds, but had probably weakened to a Category 1 storm by the time this picture was taken. Image credit: NASA.
The forecast
Passage over the rugged terrain of Madagascar has significantly weaken Giovanna, and the cyclone will move into the Mozambique Channel between Madagascar and Mozambique as a tropical storm later today. Latest computer model forecasts from the GFS and ECMWF models suggest Giovanna may reintensify over water, and swing around and pass very close to the south tip of Madagascar early next week. Meanwhile, Madagascar must also keep an eye on Tropical Cyclone Thirteen, which is gathering strength over the waters to the east of the island, and is on a course that will bring it close to Madagascar this weekend.

Thank you!
Well I hope you get some snow, I've never seen more than 6 inches of the white stuff.

================================
At 12:00 PM UTC, Tropical Depression, Former Giovanna (996 hPa) located at 23.4S 41.4E has 10 minute sustained winds of 30 knots with gusts of 45 knots. The cyclone is reported as moving west southwest at 8 knots.

Low level circulation center is now visible on satellite imagery. Convection is organized into banding pattern within a wide low level circulation, convection seems to have trouble rebuilding near the center. System is expected to keep on tracking south south-westward within the next 24 hours on the north-western edge of low to mid-level high pressures centered in the south of Réunion Island. It might rapidly intensify with good environmental conditions (weak vertical wind shear, ocean heat content very high and good low level inflow). Beyond 24 hours, a new mid-level high pressures rebuilds in the southwest of the system. The track beyond 36 hours is the result of the opposite effects of this two cells numerical weather prediction models are in rather good agreement for the track between 36 hours and 60 hours. Beyond, they are discrepancies. Some numerical weather prediction models forecast a westward track, or even northwestward, towards the Mozambique coast. Others forecast a west southwestward track and even a eastward recurve on Saturday according to ECMWF numerical weather prediction model. Present RSMC official forecast track is close to ECMWF model. However, ECMWF ensemble forecast is also highly dispersed at this tau. This important differences seem to be product by intensity forecasts that are more or less strong by different models and so a steering flow due to the opposite effects of this two cells, located at more or less high levels (low level high pressures in the south of system
According to westward tracks). Forecast uncertainty is important at tau 60 and beyond. On Sunday, landfall over Mozambique is not excluded. But now, that is not the RSMC option for official forecast track.

Additional Information
=======================
The system is a small size one, with a fluctuating structure shows now a small central dense overcast pattern.
The low level environment is not favorable, with a very poor polar inflow and quite not existing monsoon flow, and despite of quite correct upper level conditions during the next 24 to 36 hours with a good polar outflow, intensification may remain slow. Beyond this hour, the increasing vertical wind shear should limit the development of the system despite of the improving of both trades and monsoon flows.
System might continue to track west southwestward on the northern edge of the subtropical high pressures rebuilding in the south.
The next tropical cyclone advisory from Mauritius Meteorological Service will be issued at 18:30 PM UTC..

Speaking of Vermont, has anyone noticed anything *strange* in the Wunderground forecasts lately? They are reading about 10 degrees higher than anything else out there. I admit it's been a warm year but I don't think highs are going to be in the 50s next week. Either there's something wrong with the Wunderground forecasts or they are on to something no one else is.
I thought they came from the NWS.. what happened?

In what one scientist describes as “unthinkable” Environment Canada has shut off funding for atmospheric monitoring. Lidar network measurements of particle pollution layers from five Canadian stations no longer occur, and the website that was distributing this data has disappeared, according to a report in the Feb. 14 issue of the American Geophysical Union’s Eos newspaper.
“Canada is a bellwether for environmental change, not only for Arctic ozone depletion but for pollutants that stream to North America from other continents, ” said Anne Thompson, professor of meteorology, Penn State. “It is unthinkable that data collection is beginning to shut down in this vast country, in some cases at stations that started decades ago.”
I am sure government funding cuts are needed in Canada as they are here in the US, but this certainly seems like an area where the ROI is there. Perhaps there can be external funding sources to support this critical research work.

We should stay out of Syria.
There are too many opposing factions involved. It is many different terrorist groups, a terrorist government, and even if any of the civilians actually are "good guys" you can't know who's who. Of course, our naive government will try to "police" it all, which will just cost us trillions of dollars and thousands of lives for no good reason.
Best to use the good "free for all" strategy and let them fight it out.
If we don't like who wins, we can go bust them up later.
Just north of 49th parallel. Well said Neo!

On March 12, 1993, a newly formed cyclone moved into a low level baroclinic zone already in place over the Gulf of Mexico and began to rapidly intensify. The deepening cyclone turned northeastward (Fig 1.1) and the center of low pressure made landfall (Fig 1.2) in northwestern Florida during the early hours of March 13. An intense squall line (Fig 1.3) preceding a rapidly moving cold front raced across Florida with torrential downpours, wind gusts in excess of 40 m/s, 3-4 meter storm surges and 11 confirmed tornado touchdowns (Radar Loop (QT-800K)).

Also by this time, widespread moderate to heavy snows extended from Alabama to New York (Fig 1.4), virtually paralyzing the eastern third of the country. An intense pressure gradient developed from the rapidly dropping central pressure (Fig 1.5), resulting in strong winds up and down the East Coast.

When all was said and done, 270 people were dead and total property damage estimates exceeded $3 billion. According to the National Disaster Survey Report (NDSR 1994), twenty-six states were affected, impacting the lives of nearly 100 million people, approximately half the nation's population (Satellite Loop (QT-6M)).
Actually, gasoline prices are cheaper than they were at the end of the Bush regime.
Additionally, while Obama's budget has a huge deficit, you must remember that we are suffering from all the compounded INTEREST from the tax cuts on the insanely wealthy which President Bush made, as well as the failed Iraq and Afghanistan policies under Bush Jr, which his dear old Dad, Bush Senior, along with Reagan and Colin Powell left everyone, ever since going back to the first Iraq war.
You must also remember, that during America's most prosperous time period from the 50's and 60's, the taxes on the wealthy were far, far higher than they are now.
When you see a Tea Party or Replublican on television talking about tax cuts, don't be fooled, that won't help you.
And the idiot that was talking about the "999" plan by cutting income taxes to 9% but adding a federal sales tax? That would actually increase the total tax rate of the lower 50% of earners significantly. In fact, by the time you count state and local sales tax, normal people would be paying 31% tax, and the wealthy would be paying an average of about 15%, since they don't do much spending anyway the sales tax doesn't actually hit everything they have.
so in short, the Tea Party wants to rob from the poor and average and give to the rich! They don't want a middle class either, though they claim to.
They want it all for themselves.
Many of them claim to be Christians, and they are exactly the opposite of Christian social justice.
i like that picture, lol
Anyway, you might be interested to know that the U.S. produced more oil in 2010 than it had since 2003, and even more was siphoned from the earth in 2011. You might also not know that Obama has--unfortunately--opened up millions of previously off-limits acres for oil and gas exploration. You might also like to know that mining for radioactive ores has risen every year under Obama. Ditto hydroelectric. Ditto solar. Ditto wind. Ditto biofuels. (Not to mention that he ended the war in Iraq which had been destabilizing energy prices.) So please explain to us how his policies have caused energy costs to "skyrocket". I'm dying to hear...
Anyway, it's plainly obvious to all that a rapid move away from fossil fuel consumption would be immensely helpful. Imagine how it would be to live in a world where our economies weren't subject to the whims of OPEC's oil sultans. Imagine how it would be to live in a world where smog-belching vehicles weren't clogging every city. Imagine how it would be to live on a planet that wasn't headed for certain catastrophe due to rapid warming.
How anyone--other than an oil company CEO, that is--could not want a part of that world is beyond me.
--A least 10 deaths are confirmed with the passage of Giovanna
--"From the East coast we received reports of damage and human loss caused by heavy winds and flooding.” said Dominic Stolarow, UNICEF’s Emergency Coordinator in Madagascar.
--According to an impromptu aerial survey, 70% of the buildings in Brickaville have been destroyed or damaged.
--...and 60% of the buildings in the district capital of Vatomandry have been destroyed or damaged.
--Up to a million people may have suffered some of the harshest effects of the storm.
--There's currently no communication with the hardest hit areas.
Tsk tsk. ;)
You create a bunch of sock puppet accounts to plus your own posts on some obscure blog on Wunderground then you can be as obnoxious as you like on the main blog and still be there even when everyone there gives you minuses.
WU has it's own bestforecast that gives the forecast for any weather station on WUnderground. Go to a city forecast on WU. Directly under the cities name on the left it says Bestforecast & a box. If it says on in that box that is the forecast your looking at. If you want to change back to NWS forecast click where it says on & it will change it right away to the NWS forecast, & the box will say off. You can click it back on. Bestcast has been more detailed many times. Really great if you're near a PWS in a microclimate that NWS forecast always seems a little off for or you want a forecast for your PWS. It seems to be intuitive & has improved lots since it was unleashed some months ago. I've been using it mostly for a while, still toggle some between the two. It handled the recent cold here better than the NWS, though I've seen it bomb a few..especially in the early days.

TEHRAN — Iran’s Oil Ministry denied state media reports on the Islamic state stopping its crude exports to six European countries on Wednesday.
“We deny this report … If such a decision is made, it will be announced by Iran’s Supreme National Security Council,” a spokesman for the ministry told Reuters.
Iran’s English language Press TV had earlier said Tehran has stopped exporting oil to France, Portugal, Italy, Greece, Netherlands and Spain.
Maybe they made bestforecast the default setting or something.. Guess it's past time to make the leap.

Heartland operates on a range of issues besides the environment. But discrediting the science of climate change remains a key mission. The group spends $300,000 on salaries for a team of experts working to undermine the findings of the UN climate body, the IPCC.
It plans to expand that this year by paying a former US department of energy employee to write an alternative curriculum for schoolchildren that will cast doubt on global warming. The fundraising plan notes the anonymous donor has set aside $100,000 for the project.
