Hermine and Former Gaston Today – 9-7-2010

Yellow insertions by T. Ansel Toney

Here is a recent satellite image showing Hermine and the remnants of Gaston.

Gaston’s Remnant Could Redevelop Soon – 9-6-2010

RELEASED 8 AM EDT TODAY 9-6-2010

SHOWERS AND THUNDERSTORMS HAVE BECOME LESS ORGANIZED DURING THE PAST
FEW HOURS IN ASSOCIATION WITH THE REMNANT LOW OF GASTON...LOCATED
ABOUT 400 MILES EAST OF THE NORTHERN LEEWARD ISLANDS.  ENVIRONMENTAL
CONDITIONS ARE EXPECTED TO BECOME MORE CONDUCIVE FOR DEVELOPMENT
OVER THE NEXT DAY OR SO AS THE SYSTEM MOVES WESTWARD AT ABOUT 15
MPH.  THERE IS A HIGH CHANCE...70 PERCENT...OF THIS SYSTEM BECOMING
A TROPICAL CYCLONE AGAIN DURING THE NEXT 48 HOURS.  HEAVY RAINS AND
GUSTY WINDS SHOULD BEGIN TO AFFECT PORTIONS OF THE LEEWARD ISLANDS
LATER TODAY AND TONIGHT...AND INTERESTS IN THOSE ISLANDS SHOULD
MONITOR THE PROGRESS OF THIS SYSTEM.

The remains of Gaston don’t look like much this morning on the satellite imagery, but as you just read, there is a strong chance that it will redevelop into a tropical cyclonic system soon.  It is already cyclonic (loop imagery has been showing rotation for several hours now) but Weather Service experts are not ready to declare it a tropical depression on the basis of the very limited amount of current thunderstorm development.  But that is likely to change soon.  My feeling is that since it is of tropical origin and it is rotating – it should be designated a depression at this moment – but what do I know?  LOL

Unfortunately, as you can see, the models seem to favor its moving south of Hispaniola and Cuba.  This means, of course, that it’s bound for the Gulf of Mexico unless a decidedly sharp turn to the north were to occur before entering that body.  As usual, I recommend that you ignore the CLP5 model. The bottom line is that former Gaston deserves our attention.

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.”
