Arizona's fire danger to increase Saturday; Adrian hits Category 4
Posted by: Dr. Jeff Masters, 03:06 PM GMT on Juni 10, 2011 +5
The powerful winds that have fanned Arizona's massive Wallow fire into the state's second largest fire on record will remain relatively modest on Friday, and the forecast for Eastern Arizona calls for afternoon winds of just 10 - 15 mph. On Thursday, Luna, New Mexico, located about 50 miles northeast of the fire, had sustained winds that peaked at just 12 mph, with gusts to 22. These are the lightest afternoon winds the fire region has seen all week, though firefighting efforts were hindered by very low relative humidities that reached 5% on Thursday. Firefighters were able to make progress Thursday, and the Wallow fire is now 5% contained. Unfortunately, NOAA's Storm Prediction Center forecasts that critical fire conditions will return on Saturday and Sunday, with strong southwest winds of 15 - 20 mph, gusting to 35 mph. The return of critical fire conditions this weekend means that the Wallow fire will likely become Arizona's largest wildfire in history, a distinction currently held by the 2002 Rodeo-Chediski fire (732 square miles.) The Wallow fire has grown steadily from 300 square miles on Sunday to 603 square miles on Thursday--about 50% of the size of Rhode Island.

94L bringing heavy rains to the Bahamas
The large, disorganized tropical disturbance (94L) that brought heavy rains to Jamaica, Cuba, and Haiti early this week reorganized slightly overnight, and is now bringing heavy rains to the Bahama Islands. The storm killed at least 23 people in Haiti earlier this week, due to torrential flooding rains. Satellite-estimated rainfall amounts indicate 8 -10 inches of rain fell over Haiti's southwestern peninsula this week. None of the reliable computer models is showing development of 94L into a tropical depression, and NHC is giving the disturbance a 10% chance of developing by Sunday. Wind shear is a high 20 - 30 knots in the region between Cuba and South Carolina, making development unlikely. Elsewhere in the Atlantic, none of the reliable computer models is predicting tropical cyclone development over the next seven days.

Annular Adrian becomes the first major hurricane of the Eastern Pacific hurricane season
Hurricane Adrian put on an impressive bout of rapid intensification Thursday, intensifying into the season's first major hurricane in the Eastern Pacific. Adrian is the globe's 6th Category 4 or stronger tropical cyclone of the year. Adrian is expected to remain far enough offshore the coast of Mexico to not pose a threat to that country. Gradual weakening is likely through the weekend, since Adrian will be tracking over cooler ocean waters. Adrian's decay will be slower than usual for a hurricane, since it has become what is called an annular hurricane. Annular hurricanes feature a large eye surrounded by a very thick eyewall, with no spiral rain bands. The very thick eyewall makes annular hurricanes resistant to weakening due to wind shear, dry air, or cool waters. Annular hurricanes are rare; only 3% of all Eastern Pacific tropical cyclones become annular, and 1% of all Atlantic ones.

A record 100-year flood on the Missouri River
The greatest flood in recorded history is occurring along sections of the Missouri River, which runs from Montana to St. Louis, Missouri. On Thursday, the river hit 28.0' feet at Williston, North Dakota, surpassing the record flood height set in 1912. The river is expected to continue to rise to 1.4' above the 1912 mark by Tuesday. This week, the Missouri River at Omaha, Nebraska surpassed the level set during the great 1993 flood, and the river's height is currently the 2nd greatest on record, 9' below the mark set in 1952. Water releases at the six flood control dams on the Missouri River are now at more than double their previous all-time highs; these dams were built between 1940 and 1964. This great 100-year flood on the Missouri River is just beginning, and is likely to cause major damage over the next few weeks.

Have a great weekend everyone, and I'll be back Monday with a new post.

India Meteorological Department
Tropical Cyclone Advisory #2
DEPRESSION ARB01-2011
23:30 PM IST June 11 2011
====================================

At 18:00 PM UTC, Depression ARB01-2011 over northeast Arabian Sea off Maharashtra-South Gujarat coasts remained practically stationary and lays centered near 20.0N 71.5E, or about 180 km northwest of Mumbai (India), 150 km southeast of Veraval (India/Gujarat), and 700 km southeast of Karachi (Pakistan). It may intensify further and move slowly northwestward.

As of 12:00 UTC/17:30 IST
-----------------------
3 minute sustained winds near the center is 25 knots with a central pressure of 996 hPa. Winds are stronger over the southern part under the influence of the monsoon surge. The state of the sea is rough to very rough around the system center. Satellite imagery indicates gradual organization of convection during past 12 hours. The Dvorak intensity of the system is T1.5. Associated intense to very intense convection (Cloud Top Temperature is -77C) lies over Arabian Sea between 16.5N to 21.0N and east of 65.5E.

Vertical wind shear of horizontal wind over the region is low to moderate (10-20 knots). The system lies to the south of tropospheric ridge, which roughly runs along 24.0N. Sea surface temperature is also favorable for intensification as it is 30-32C over the region. The relative vorticity at 850 HPA level and upper level divergence are also favorable for intensification. However, the ocean heat content is less than 60 kj/cm2 over the region which does not favor intensification. The MJO is lying in phase 4, but with lower amplitude (>1) according to both statistical and dynamical forecast, it is expected to be in phase 4 and 5 next 3-4 days. It may not be favorable for amplification of convection and hence intensification of the system.

There is no consensus by the numerical weather prediction models for intensification and movement of the system. Considering all the above, the system is expected to intensify gradually and move initially northwestward during the next 24 hours.

I'm thinking MJO will be back quicker than the models are saying. Looks very similar to what they did last time, as they were saying that no activity was going to occur. Even the plots of previous activity were incorrect, and some still are. Around June 18th-20th seems like a good estimate for when activity will pick up, models say a week or two later though.



That's an empirical probability model based on a perfectly "well-behaved" MJO. It is not a dynamic forecast.

According to NCEP reanalysis, the last very dry decade in Florida was the 1970s. However, that decade had the opposite multidecadal signals (PDO and AMO) that we have now, which suggests that they may not be the root of the issue. It's an intriguing problem.

Those were well established with a good root system, can tell by looking at them by how big they were, and they had ground cover on the ground which should of protected the soil moisture even more for them. And it's only getting worse.

And...1-2 inches of rain fell late this morning just a few miles from me and this location.....nothing for us

3. What link?
4. If the current trends hold, it could happen.

This is why I keep saying that Historical weather statistics may prove to be completely irrelevant in the near future.
There are all sorts of new influences working Globally that affect Weather, and we have not begun to understand them, far less factor them into the equation.

Sahara Dust is a good example.
The research is still not conclusive re; it's affect on T-Waves and so on.

The study of Weather and Climate is a particularly difficult one since we absolutely cannot duplicate conditions in the Laboratory....
