Drought conditions developing across SW Louisiana, May 22, 2014.
The latest Drought Monitor was released on Thursday and it confirms what we know – drought conditions are developing across Southwest Louisiana. Moderate to severe drought covers areas from Lafayette westward. The rain deficits are substantial year-to-date. Lafayette is down 7.23″ for the year thru Thursday, while Lake Charles is down 9.33″ compared to normal. There is little hope for any rainfall until the middle of next week when some energy above may move into the state.
Hurricane season 2014 is almost here and we’re helping you get prepared. We’ve put together a fantastic half-hour special featuring interviews from Dr. Rick Knabb and Dr. Phil Klotzbach, details on how tropical cyclones are steered in the atmosphere, tips on preparing for an approaching storm, and much more. Tune in Saturday, May 31 at 6:30 PM or Sunday, June 1 at 11:30 AM. If you can’t watch live, make sure to set your DVR. This is a top-quality special produced right here at News 10! Remember, as the season progresses, keep checking back to livedoppler10.com and we’ll post in-depth analysis on tropical systems across the Atlantic Basin.
Tuesday’s low of 20° at Lafayette was the coldest reading in four years and as cold as we’ve been in almost 18 years! The last time the temperature dropped into the teens was on February 5, 1996, when we hit 16°. There are a lot of similarities between the winter of ’95-’96 and ’13-’14, including a long-wave ridge over the Northern Pacific and persistent troughing over North America. Early 1996 featured a low of 21° in January at Lafayette, an 18° and 16° low in February, and a late 25° low on March 9. If we use 1996 as a guide, more bitterly cold air may be in store for South Louisiana before this winter departs.
Data revealed at an American Geophysical Union scientific meeting in San Francisco Monday is record-breaking. NASA satellite data shows the temperature in East Antarctica in August 2010 hit -135.8° F. On July 31, 2013, the temperature there hit -135.3°. The world record had been -128.6°. That is cold!!! By the way, the record for heat was set way back on July 10, 1913, when a thermometer recorded 134° at Death Valley, CA.
The 2013 Atlantic Hurricane Season came to an end over the weekend. The final numbers include 13 named storms, two of which became hurricanes (Humberto & Ingrid), with neither becoming major hurricanes. While the number of storms was above the average of 12, the number of hurricanes and major hurricanes was well below normal. Unfavorable conditions dominated much of the season, with strong wind shear and dry and/or dusty conditions. The last time the US was hit by a major hurricane was back in October 2005 (Wilma). The eight-plus year gap is more than twice as long as any other gap between major hurricane hits since records began.
The rain-maker impacting Acadiana Monday/Tuesday will turn into a big storm for the East Coast on Wednesday, which is typically the busiest travel day of the year. Air travel to the big cities in the Northeast and thru hub cities like Atlanta, may experience significant delays. In the wake of the system we’ll see plenty of sunshine as chilly air grips most of the country.
If Super Typhoon Haiyan were in the Gulf of Mexico, here is some perspective on its massive size. Maximum sustained winds were around 195 mph, stronger than Camille’s 190 mph max sustained winds in 1969.
Super Typhoon Haiyan hit the Philippines on Thursday (our time) with max sustained winds of 195 mph. This tops Hurricane Camille in 1969, which had max sustained winds of 190 mph at landfall. While reliable records are very limited regarding tropical cyclones, Haiyan will take over the #1 spot as the strongest. However, there is no way to say for sure that Camille wasn’t stronger as all instruments were destroyed at landfall and satellite instruments that can estimate winds weren’t developed at the time.
Super Typhoon Haiyan made landfall on Thursday our time, packing maximum sustained winds of 195 mph with gusts to 235 mph. The monster may produce a storm surge of 20-25′, likely devastating the Central Philippines. While the Atlantic Basin has been rather tranquil this year, tropical activity on the other side of the world has been much more widespread.
This is pretty cool. The visible satellite image Monday afternoon showed a distinct cloud line across Eastern Louisiana. This had to do with very humid air meeting very dry air around 4,000-5,000 feet in the sky. We definitely don’t see such a sharp cloud boundary like this too often over such a large distance.
