GFS Model Forecasts for Hurricane Earl







The GFS weather forecast model continues to indicate that a strong trough will move into the Northeast from the Midwest and stear Hurricane Earl out to sea to the northeast on Friday of this week. Clouds and showers may graze New York City with a better chance for tropical showers over eastern Long Island. Strong rip currents and rough seas will keep boats and bathers out of the water at all area beaches as this very strong storm tracks up the east coast. More on this storm later in the week.

Latest on Hurricane Earl...Now a Category 3 Storm



This is the latest hurricane discussion and forecast track from the National Hurricane Center.

HURRICANE EARL DISCUSSION NUMBER 21
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072010
1100 AM AST MON AUG 30 2010

THE EYE OF EARL HAS BECOME BETTER DEFINED IN VISIBLE SATELLITE IMAGERY THIS MORNING AND IS WELL-DEFINED IN RADAR IMAGERY FROM BOTH SAN JUAN AND ST. MAARTEN. AN AIR FORCE HURRICANE HUNTER AIRCRAFT MEASURED 700 MB FLIGHT-LEVEL WINDS OF 111 KT IN THE NORTHEAST EYEWALL AROUND 1200 UTC. THE AIRCRAFT HAS NOT SAMPLED THE NORTHEASTERN QUADRANT AGAIN...BUT FOUND 90 KT SFMR WINDS IN THE NORTHWEST EYEWALL AND A MINIMUM PRESSURE OF 960 MB. THIS SUPPORTS INCREASING THE INITIAL INTENSITY TO 105 KT...CATEGORY THREE ON THE SAFFIR-SIMPSON HURRICANE WIND SCALE. THE LOW SHEAR AND WARM WATER ENVIRONMENT AHEAD OF EARL APPEARS CONDUCIVE FOR ADDITIONAL STRENGTHENING DURING THE NEXT FEW DAYS. THIS SUPPORTS KEEPING EARL AT MAJOR HURRICANE STRENGTH DURING THAT TIME...ALTHOUGH EYEWALL CYCLES COULD INDUCE SOME FLUCTUATIONS IN INTENSITY. THE OFFICIAL FORECAST IS AT THE UPPER END OF THE INTENSITY GUIDANCE. LATE IN THE FORECAST PERIOD INCREASING SHEAR AND COOLER SSTS SHOULD INDUCE
WEAKENING.

THE INITIAL MOTION REMAINS 285/13. EARL IS EXPECTED TO TURN TOWARD THE NORTHWEST WITHIN THE NEXT DAY OR SO AS IT MOVES AROUND THE WESTERN PERIPHERY OF THE SUBTROPICAL RIDGE DURING THE NEXT COUPLE OF DAYS. AFTER THAT TIME...EARL IS FORECAST TO TURN NORTHWARD...THEN NORTHEASTWARD AHEAD OF A MID-LATITUDE TROUGH THAT MOVES ACROSS THE GREAT LAKES AND INTO THE NORTHEAST UNITED STATES IN 4-5 DAYS. THE TRACK GUIDANCE HAS SHIFTED WESTWARD AGAIN AND THE OFFICIAL FORECAST HAS BEEN ADJUSTED IN THAT DIRECTION. THE UPDATED TRACK FORECAST IS NEAR THE MIDDLE OF THE TIGHTLY CLUSTERED GUIDANCE.

THIS IS A GOOD TIME TO REMIND EVERYONE THAT NHC AVERAGE TRACK FORECAST ERRORS ARE 200 TO 300 MILES AT DAYS 4 AND 5. GIVEN THIS UNCERTAINTY...IT IS TOO SOON TO DETERMINE WHAT PORTION OF THE U.S. EAST COAST MIGHT SEE DIRECT IMPACTS FROM EARL.

Rare Fire Tornado in Brazil

From Digital Journal:

San Paulo - A fire tornado has been caught on video near Sao Paulo, Brazil, where the humidity is almost desert-like. This rare phenomenon is caused by brush fires and dry winds. Fire tornadoes form when a warm updraft and wildfire meet. They are usually 30-200 feet tall, 10 ft wide, and last only a few minutes. However, some can be more than 1/2 mile tall and persist for more than 20 minutes. The largest on record occurred in 1923, when a giant fire tornado was ignited by an earthquake in Tokyo which led to the deaths of 38,000 people in 15 minutes. Wild fires have tripled this year in Brazil. Burning trees, an outdated method of razing the forest for crop fields is still being used. Although federal laws have been passed to ban the practice, it is also commonplace for sugarcane fields to be burned prior to harvest to "facilitate harvesting, fertilize fields with ash and remove venomous animals and reptiles".
