Earl long gone, but tropics stay active

Posted by Sheena Parveen under Daily updates

Tropical Storm Earl’s last advisory from the National Hurricane Center was issued Saturday night at 11pm.  This system has continued North through Canada as post-tropical.  Weakening is expected in the next 48 hours but it’s still packing tropical storm force winds through parts of Canada.

The last track was issued at 11pm Saturday night.

We are still keeping an eye on the remnant low pressure area of Gaston, as it could regenerate into a tropical depression in the next couple days.  It is a very small system, located about 750 miles East of the Leeward Islands.  A newly developed area of low pressure is in the SW Gulf of Mexico.   This one is Invest 90L.  Conditions appear favorable for development of this tropical wave, but land interaction will occur soon as it moves NW, so any development will be short-lived.

The remnant low of Gaston will continue on a Westward track, entering the Northern Caribbean Sea in a few days.  Currently the system isn’t well organized, but conditions appear favorable with lighter windshear in the forecast.

Invest 90L is expected to continue NW across the Gulf of Mexico where conditions are becoming more favorable for development.  But, since it will reach land soon, potential would be cut off at that point.

Wind shear is relatively moderate through the Atlantic and Caribbean, but will become more favorable and much lighter next week, when we could see another tropical system move off West Africa.

The GFS model isn’t developing the remnant low of Gaston as much as it was yesterday, but it does pick up on a stronger tropical system moving through the Atlantic by Friday, September 10th.  Right now, that system isn’t in the Atlantic, so we’ll keep watching for you.
