Tropics quiet as season winds down

Posted by Jim Weber under Daily updates

The tropics are quiet once again not that Ida has passed. It has not been a very active season to say the least and the view across the Tropical Atlantic continues to look very quiet.

The ITCZ has a few clusters of disorganized thunderstorms. There is also a disorganized are north of Puerto Rico which we have seen for several days. This is associated with a cold core (non-tropical) low and shows no signs of organization. The Caribbean is virturally cloud free along with a band of clouds in the Gulf which is associated with a dissipating cold front.

Caribbean water temperatures are in the low to mid 80s which is still warm enough for tropical development but a large ridge and dry air has dominated most of the Gulf and Caribbean over the past several days.

This subsidence will continue to keep the Caribbean cloud free for the next couple of days. During the month of November we normally watch the western Caribbean for tropical development and those systems that do develop normally move towards the NE and into the Atlantic.

With just a couple of weeks left in the season it is quite possible we have seen the last of Hurricane Season 2009.
