Tropical Depression Nine Forms in the Gulf

Oct 22, 2014 3:11 AM

An area of disturbed weather in the Bay of Campeche finally became organized enough to warrant an upgrade to Tropical Depression Nine late Tuesday evening.

Tropical Depression Nine will slowly track eastward over the next 12 to 24 hours before making landfall on Mexico's Yucatan Peninsula this evening. Despite its close proximity to land, the Gulf waters are very warm with temperatures well into the 80s. Thus, Tropical Depression Nine should strengthen into Tropical Storm Hanna before making landfall.

The main impact across the Yucatan over the next several days will be heavy rainfall that can cause flash flooding. After Hanna crosses the Yucatan, it should weaken back into a tropical depression as it then enters the northwestern Caribbean sometime on Friday.

Beyond this time, Hanna should continue to drift eastward or even slightly south of east as it tracks across the western Caribbean, likely remaining south of Cuba.

Elsewhere across the basin, a tropical wave will move through the Windward Islands Wednesday and Thursday, but strong wind shear will keep this feature from developing.

The area of low pressure near the Azores and Canary Islands continues to drift westward. Thunderstorms associated with this feature are not wrapping around the center of circulation and it remains a non-tropical system.

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
200 AM EDT WED OCT 22 2014

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Nine, located over the Bay of Campeche.

A large non-tropical low located over the far eastern Atlantic
Ocean, a few hundred miles south of the Azores, is producing
disorganized thunderstorms and winds to gale force.  This system
could still acquire some subtropical characteristics during the next
day or so while it moves westward to west-southwestward at 10 to 15
mph.  Upper-level winds are forecast to become less conducive for
subtropical or tropical cyclone formation by tonight, and
development after that time is not likely.  Additional information
on this system can be found in High Seas Forecasts issued by Meteo
France.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

Hurricane Features

  • What is the Saffir-Simpson Wind Scale?

    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.

  • Atlantic Category 5 Storms

    To qualify as a Category 5 hurricane on the Saffir-Simpson hurricane intensity scale, maximum sustained winds must exceed 155 mph (135 kt).

  • Retired Hurricane Names

    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.

  • Download Hurricane Tracking Maps

    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.

  • When and Where Do Hurricanes Occur?

    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.
