Tropical Storm Vince
Tropical Storm Vince's formation today marks the first time that a storm beginning with the letter "V" has been given name. With 20 named storms, the Hurricane Season of 2005 is now in sole possession of second place on the list of busiest hurricane seasons of all time. Only 1933, with 21 storms, had more (back before they started naming storms). Vince formed in a very unusual location, not far from the coast of Spain, and in a region where water temperatures are only 23 - 24 C. I know I always harp on the rule that a water temperature of at least 26C is needed for tropical storm formation to occur, but we can bend that rule a little when a tropical storm forms from a pre-existing non-tropical low pressure system that sits over water for many days, and gradually acquires a warm core. As we've already seen, the Hurricane Season of 2005 doesn't care much about what is usual, and Vince's formation is certainly ample evidence of that. The storm was too far east to fit on our newer tracking maps, and just barely appears on one of our old tracking charts I had to dust off this morning, special for the occasion!
Vince won't be with us for long. A cold front approaching Europe will pick up Vince Tuesday morning, and cold water and wind shear will tear Vince apart. Vince's remains should bring Portugal and Spain heavy rains and winds gusts to 45 mph on Tuesday. Portugal gets the remains of tropical storms every 5 - 10 years, on average. This occurred most recently in October 1998 with Jeanne.
Subtropical Depression 22
Subtropical Depression 22 dissipated Saturday evening, torn apart by wind shear. Its remnants will continue west towards the Carolinas, but are not expected to regenerate or bring significant rains to the U.S., as the wind shear is too high (30 knots) for re-development to occur.
What's behind TD 22?
The tropical disturbance we've been following near 15N 53W, about 450 miles east of the Lesser Antilles Islands, has a low level circulation, but the cloud pattern is disorganized. Development is not expected today or Monday, but some slow development after that is possible.
A strong upper-level low north of Puerto Rico is creating a large curved band of disturbed weather from the Bahamas through the central Caribbean to the Leeward Islands. No development is likely in this area until Tuesday, when the low is expected to weaken and move north and reduce the amount of wind shear over the area. Several of the computer models predict that a tropical storm could form from this disturbed area of weather by mid-week and move north to threaten Bermuda.

There is no new news on Stan's death toll today, which remains at about 1500. Stan now ranks as one of the 30 most deadly hurricanes of all time. Stan now surpasses Katrina as the most deadly hurricane of 2005; Katrina's death toll stood at 1242 at last count, with 1003 of the deaths in Louisiana.

The grim task of recovering bodies in Guatemala continues today, where the entire town of Panabaj in western Guatemala was buried in a landslide, killing all 800 residents. The entire village may be declared a mass grave, as rescuers move on to find victims of more survivable mudslides. Another 600 died in mudslides elsewhere in Guatemala. The storm also killed 67 people in El Salvador, 24 in Mexico and 11 in Nicaragua. Hundreds more are missing and presumed buried under landslides near Lake Atitlan in Guatemala.
The next update will be Monday around 10 am.
