Volcanic eruptions in Chile and Africa disrupt aviation; Arizona fire nears record
Posted by: Dr. Jeff Masters, 15:23 GMT le 13 juin 2011 +6
Eastern Arizona's massive Wallow Fire grew to 700 square miles over the weekend, bringing it very close to being Arizona's largest fire on record. The 2002 Rodeo-Chediski fire (732 square miles) currently holds that distinction. However, NOAA's Storm Prediction Center forecasts that critical fire conditions will spread over Eastern Arizona and Western New Mexico this afternoon. Strong southwesterly winds of 15 - 20 mph are expected, with very low relative humidities of 5 - 15%. With the Wallow Fire just 10% contained, this means that the fire will likely expand significantly today and become Arizona's largest fire on record. Firefighting conditions are expected to improve on Tuesday and Wednesday, with much weaker winds, but stronger winds may return again on Thursday. A separate fire burning in Southeast Arizona, the Horseshoe Two fire, has grown to 200 square miles, and is 40% contained. This is Arizona's 5th largest fire on record.

The Earth is active
We now have two volcanic eruptions that are emitting large ash clouds causing significant disruptions to aircraft flights. Last week, the Puyehue-Cordón Caulle volcano in Chile erupted, sending aloft an ash cloud that circled the Southern Hemisphere, canceling flights thousands of miles away in Australia and New Zealand. At approximately 5pm EDT on Sunday, a new major eruption occurred in Africa at Eritrea's Nabro volcano. This volcano has no eruptions in historical records, but sent an ash plume over 21,000 feet (13 km) high over Eritrea after an earthquake of magnitude 5.7 rocked the area. The ash has now spread to the northwest over Sudan, and is expected to spread to the north over Egypt later today. On Tuesday, the ash is expected to get caught in a west-to-east jet stream flow, and spread over much of the Middle East. The latest forecasts from Meteo France (Figure 3) show impacts to Israel, Saudi Arabia, Jordan, and Iraq on Tuesday morning. The latest MODIS image from NASA shows the plume nicely.

Figure 3. Forecast issued at 8am EDT by Meteo France showing the expected spread of the ash plume from Eritrea's Nabro volcano. Ash between 35,000 and 45,000 feet altitude (light dashed lines) is predicted to move over the Middle East, including southern Israel, by 2am EDT (0600 Z) on Tuesday, June 14. The volcano is mis-identified as the Dubbi volcano on this image.

The Atlantic is quiet
In the Atlantic, none of the reliable computer models is predicting tropical cyclone development over the next seven days.

Good morning Aqua, I went tubing yesterday at Ichetucknee Springs, was good fun. On the rain front we had about .75 inches.
Smoke is as you say forcast for today. Last night before the storms the smell of smoke was the highest I've experienced this year.

Scott declares wildfire, drought emergency in Fla.

The Associated Press

TALLAHASSEE, Fla. -- Gov. Rick Scott has declared a state of emergency in Florida due to wildfires and drought conditions.

The declaration Monday puts the state Division of Emergency Management in charge of the situation.

That includes deploying personnel and resources of the Florida National Guard and other state and local government agencies.

The order notes extreme to exceptional drought conditions are expanding across southeastern and north Florida. They are expected to worsen in the new few weeks.

More than 300 active wildfires were burning on about 115,583 acres across the state Monday.

A small brush fire in Brevard County that was contained from last week flared up on Monday and jumped the fire lines. The fire moved into Volusia County and quickly consumed over 1200 acres burning at-least 10 homes and 38 hunting camps. The fire is 0% contained.

Woke up to the smell of smoke outside this morning, emcf.
VOLUSIA COUNTY, Fla. -- Fire crews are monitoring 30 different wildfires burning in Volusia County. WFTV learned that residents are going to be dealing with all of these fires for months to come.

No matter how many tractors or thousands of gallons of water, officials said it could be months before thick smoke and flames go away for good.

"This is a mother nature thing that is going to take us inches of rain to get us out of this,” said an official....

SUGGESTS THAT A DEVELOPING WAVE OF LOW PRESSURE OVER THE WESTERN
CARIBBEAN WILL ADVANCE NORTHWESTWARD THROUGH THE PERIOD

INCREASING DEEP LAYER MOISTURE AND THE CHANCE FOR SHOWERS AND
THUNDERSTORMS, ESPECIALLY SATURDAY INTO SUNDAY. MID LEVEL RIDGING
OVER THE LOWER MISSISSIPPI RIVER VALLEY WILL PUSH SOUTHEAST

Sorry for the downtime. I haven't heard the final report yet, but initial indications were that a fiber cut in San Francisco was responsible.

The long-range GFS obviously shouldn't be taken too seriously. However, it has proven to be a useful tool in the past when it is very consistent on a specific pattern in the long range. That kind of a hint can cue a forecaster into other things that may result in some kind of outcome. The goal is to find that outcome. The GFS is only one piece to the puzzle, and we very well may lose that piece if the model suddenly becomes inconsistent, which happens a lot.

Sodden state to get even wetter as rains continue
NSW is coping a battering from the elements, with rain and heavy winds expected to continue for the next 24 hours.

The NSW mid-north coast is coping the worst of it, with Red Rock's Bowling Club losing most of its roof in a wild storm this morning.

The Daily Examiner reports that residents up to half a kilometre away heard a large explosion as iron from the roof cut the town's power supply.

Grinspoon bassist Joe Hansen was one of the locals who heard the roof come off, which woke him up.

He said it sounded like a "super loud bang", which was over in just seconds.

"A twister or something like that had come through...it was pretty full on," he said.
A Corindi SES spokesperson said a large weather system and strong winds ripped through the town and caused damage at Corindi and nearby Red Rock where the local bowling club lost some of its roof.

The SES has received 330 requests for assistance, with 86 per cent of these now complete, since the event began on Monday.

Most of the calls have been for leaking roofs, roof damage and sandbagging requests as well as trees down.

The Central Coast and the Hunter have been the areas with the hardest hit, although emergency services workers will today shift their focus the mid north coast.

Rain is continuing to batter the mid-north coast today and is expected to continue for the next 24 hours.

According to BOM up to 115mm(4.53in) of rain has fallen during the past 48 hours to 9 am today. However, the rain intensity has increased during the past nine hours, with 50mm falling during this period.

Further heavy rain is forecast for the next 6 to 12 hours.

This rain is expected to cause minor to moderate flooding along the Macleay River at Georges Creek, Bellbrook and Kempsey from this afternoon onwards.

The flood warning for Bellinger River has been upgraded to moderate with up to 100mm(3.94in) of rain forecasted for the next 12 hours.

Although rain has eased since 6am today, further heavy rain in the order of 50 to 100 millimetres is forecast for the next 12 hours.

According to the Bureau of Meteorology (BOM) a broad low pressure system is deepening on the northern coast of New South Wales.

A line of continuous heavy showers and thunderstorms is tracking in from the east in the Coffs Harbour/Woolgoolga area focusing some of the highest falls in this area for the next few hours, but homes have not been inundated at this stage.

Over the next 24 hours, BOM said the heaviest rain would remain south of this low centre over the Mid North Coast, Hunter Valley and eastern parts of the Northern Tablelands.

Further south there are about 50 rural properties isolated west of Kempsey and Port Macquarie due to closure of country roads.

There is widespread flooding on the Pacific Highway between Grafton and Kempsey and the potential for flash flooding in northern parts of the state.

Since 9am yesterday Wooli Creek has received 170mm of rain, Bellingen 159mm(6.26in), Yamba 155mm(6.10in) and Coffs Harbour 123mm(4.84in).

There are flood warnings for a number of rivers including the Hastings Manning, Orara and Nambucca.

What is important to follow is if other models join the GFS scenario in next runs. If that occurs, then we have game on!

Yes, though it is also fun to try to beat the models to it, and decide whether the GFS scenario could hold water or not. That's why other clues exist besides the GFS.

Kempsey residents ordered to evacuate
Tuesday June 14, 2011 - 19:55 EST

The State Emergency Service has issued an evacuation order for businesses and residents in the Kempsey CBD, as the flood situation worsens.

The Kempsey Bridge is predicted to reach 6.4 metres(21ft) between 1:00am and 3:00am (AEST), which could cause the levee to overtop.

This could lead to inundation of the city centre and residents are being advised to evacuate within the next four hours.

Meanwhile, SES crews are keeping a close eye on river levels in other parts of the mid north coast, as heavy rain continues to fall across the region.

Flood warnings are current for the Bellinger, Nambucca, Orara, Macleay, Hastings and Manning Rivers, with water levels continuing to rise in some areas.

This afternoon the SES began evacuating around 400 residents in villages across the Lower Macleay as a precaution, saying those areas will become isolated later this evening.

Near Bellingen about 800 residents remain isolated in the Thora Valley.

The SES rescue officer Bill Shipp says it will be a while before the river falls.

"It could be a couple of days," he said.

"Because it takes a fair while for the water to come down - that's if the rain stays as it is, but if it gets more rain coming it could take a bit longer."

Further rain is forecast, with the severe weather expected to move slowly south.

The weather bureau is also forecasting dangerous surf conditions for coastal activities, such as swimming, surfing and rock fishing.

I got a bit or rain yesterday too (W. Lake Worth, FL), but only about .15". I have a rain barrel set at one of our rain gutter down spouts and know that it takes ~.25" to fill up the 55 gal drum with roof run-off. It's about 2/3 filled. Hopefully we'll get some more today.
