LATEST ON GASTON – 9-3-2010

Gaston has weakened to the point where it has lost its closed rotation.  This means it has returned to the status of tropical wave (synonymous with tropical disturbance).  However, some of the more dependable computer models expect it to regain strength soon.  My advice is to ignore the CLP5 track in the chart above; it is a baseline derived from recent directional tendencies and is used as a tool “after the fact” to evaluate the accuracy of the more analytical models.

You have probably noticed that I tend to focus on those storms which could be a threat to Florida and the Gulf Coast and once that threat passes I generally assume that you get plenty of continuous information from television news.  Though it is quite repetitive and there is some “drama” I still highly recommend the Weather Channel.  Here is a link to their Hurricane Central page:  http://www.weather.com/newscenter/hurricanecentral/

We have friends in our West-Central Florida neighborhood, wonderful people, who are currently in Nova Scotia.  Therefore, since some of my concerned neighbors consult this site, I’m including this current statement about Earl’s expected effect upon Canada.  This comes verbatim from the WeatherUnderground website, appearing in Dr. Jeff Masters’ web-log (11:54 am EDT):

Impact of Earl on Canada

“Winds will begin to rise on the southwest coast of Nova Scotia late Friday night and early Saturday morning. By late morning Saturday, Earl is expected to make landfall somewhere between the Maine/New Brunswick border and central Nova Scotia. At that time, Earl will probably be a strong tropical storm with 55 – 60 mph winds. Earl will be moving at a very rapid 25 – 30 mph when it arrives in Canada, and regions on the right side of the eye can expect winds 15 – 20 mph greater than on the left side, due to the fast forward motion of the hurricane. Earl’s impact is likely to be less than 2008’s Hurricane Kyle, the last hurricane to hit Nova Scotia. Kyle hit near Yarmouth, Nova Scotia, as a Category 1 hurricane with 75 mph winds. Kyle produced a storm surge of 2.6 feet, and did $9 million in damage to Canada. The 11am EDT NHC wind probability forecast is calling for a 15% chance of hurricane-force winds in Yarmouth, and 3% in Halifax.”

PUERTO RICO REPORTS – MORE FLOODING, LANDSLIDES – TROPICAL DISTURBANCE LIKELY TO HEAD NORTHWARD

THIS IS A TIME-SENSITIVE POST

FROM SEPTEMBER 22, 2008

Dr. Jeff Masters of http://www.wunderground.com/tropical/ reports flash floods and mudslides in Puerto Rico from the tropical disturbance in their vicinity.  Please check it out.  His weather blog is excellent.  You will find it on the right side of the page.

The models are all over the place today.  The GDFL model has been, in my opinion, the best performer over the last couple of years at least.  Please disregard the CLP5 model and the XTRP model.  They are no-skill models that do have a useful purpose but they are not meant to convey an actual forecast.  One day I may write about those models to explain their function but if you are bugged by it and can’t wait, I suggest a Google search.

Please visit the rest of this web-log at https://cloudman23.wordpress.com/.  If you are interested in weather, there are some tutorial items scattered about and more will be added in time.  At the end of this page there is a cue to click to the previous page or the next page.
