Western Caribbean disturbance 98L a threat to develop; Otto weakening
Posted: 9:48 AM EDT on October 09, 2010
An area of disturbed weather is in the Western Caribbean, a few hundred miles east of the coast of Nicaragua. The disturbance has a modest and slowly increasing amount of intense thunderstorms, and is showing some spin. The disturbance is drifting northwest, and has a 20% chance of developing into a tropical depression by Monday morning. Several of the computer models call for this disturbance to intensify into Hurricane Paula and hit Cuba by Wednesday, but these forecasts are probably too aggressive.
Looks like the computer guesses are looking more toward the Yucatan-Cuba area but the Bay of Honduras has not been ruled out...
The Invest 98 computer chart still works even after the naming. Here's the zone of hate path...from Dr Masters...
Proximity to land is hampering Paula's ability to intensify some, and the storm's northwest movement of 10 mph will take the center far enough away from the coast of Honduras this evening to substantially increase the storm's ability to intensify. The latest SHIPS model forecast calls for wind shear to stay mostly in the moderate range, 10 - 15 knots, through Tuesday afternoon, then increase to the high range, 20 - 25 knots, for the remainder of the week. The computer models predict Paula will continue on a northwest motion then turn more north-northwest on Wednesday, which would take the storm close to landfall on the coast of Belize or Mexico's Yucatan Peninsula Tuesday night or Wednesday morning. At that time, Paula may be approaching Category 2 hurricane status, due to the moderate wind shear, SSTs of 29°C, and a sufficiently moist atmosphere. On Wednesday, there is considerable doubt about the future path of Paula. Steering currents in the Western Caribbean will collapse, potentially allowing Paula to wander in the region for many days, as predicted by the GFS and HWRF models. It is also possible that Paula will push far enough inland over Mexico's Yucatan Peninsula that the storm will dissipate, as predicted by the NOGAPS model. Finally, if Paula grows strong quickly, and pushes far enough north, it could get caught up a strong trough of low pressure predicted to traverse the U.S. this week (and spawn a Nor'easter for New England this weekend.) In this scenario, offered by the GFDL model, Paula would make a sharp turn to the east-northeast, hit western Cuba, bring tropical storm-force finds to the Florida Keys on Thursday, then move into the Bahama Islands by Friday or Saturday. It is too early to say which of these scenarios is the most likely, as the storm is just forming and the models do not have a good handle on it yet. Regardless, northern Honduras, Belize, and Mexico's Yucatan Peninsula will receive dangerous flooding rains from Paula today through Wednesday.
Yeah, weekends are transition days on Roatan, and oddly some of the computers send her back down after a u-turn, but way too early to worry. Maybe she will breakup inland.Thanks Don. I am supposed to be in Roatan Saturday, so I hope Paula gets off her broomstick and follows a north track.
