Strong Shear Across The Tropics
Oct 24, 2014 5:36 PM
A strongly sheared area of low pressure near Andros Island in the Bahamas will rapidly track to the east-northeast tonight and heavy rain will end over the northern and central Bahamas. The low pressure center will pass just south of Bermuda Saturday night and it will cause a round of heavy rain across the islands later Saturday and Saturday night. Amounts should average 0.50 to 1.00 inches, with some local amounts of 2.00 inches so this will impact clean up efforts from Hurricane Gonzalo.
The sheared remains of Tropical Depression 09 are located near lower Yucatan coast and they will slowly shift east and south through the weekend before stalling near the Honduran or Nicaraguan coast early next week. Since waters are quite warm and there is less wind shear near the Honduran coast, there is some chance of reorganization later this weekend or early next week. However, dry air to the north of the system and interaction with the Central American coast will be inhibiting factors.
High pressure currently over Texas will shift east across Florida early next week before reaching Bermuda by midweek. This will the steer the system into central America or perhaps back into the lower Yucatan Peninsula. The American global model shows the system getting into the southern Bay of Campeche later next week while the European model keeps it over southeast Mexico. The main impact from this system will be heavy rain over parts of central America and the Yucatan Peninsula through next week.
A large tropical wave about halfway between the Cape Verde Islands and the Lesser Antilles will struggle to develop due to strong wind sheer aloft.

The Saffir-Simpson Wind Scale is a categorical classification of hurricanes based on their wind speed, used by the U.S. government's National Hurricane Center.
To qualify as a Category 5 hurricane on the Saffir-Simpson hurricane intensity scale, maximum sustained winds must exceed 155 mph (135 kt).
Hurricanes that have a severe impact on lives or the economy are remembered by generations after the devastation they caused, and some go into weather history.
AccuWeather.com has created a number of specialty maps designed for tracking the progress of tropical storms and hurricanes. Use these maps in conjunction with our Hurricane Position graphic, as well as statements issued by the NHC with storm positions.
Hurricanes (by whatever name) are by far most common in the Pacific Ocean, with the western Pacific being most active. In some years, the Philippines are struck by more than 20 tropical storms and typhoons.
