Tropical Disturbances Today

Disturbance 1. Hurricane Earl

Hurricane Earl, located a few hundred miles south of Bermuda, is moving toward the north near 10 mph.  A turn toward the north-northeast with a further increase in forward speed is expected today, followed by a turn toward the northeast on Friday.  On the forecast track, the center of Earl is expected to pass to the southeast of Bermuda this evening and tonight. A Hurricane Watch and a Tropical Storm Warning are in effect for Bermuda. 

Disturbance 2. Post-Tropical Cyclone Danielle

Recently downgraded Tropical Storm Danielle is located several hundred miles north-northwest of the Azores and is forecast to remain a large post-tropical cyclone over the north Atlantic for the next several days.

Disturbance 3. Central Tropical Atlantic

An area of low pressure is located almost a thousand miles west-northwest of the Cabo Verde Islands. Environmental conditions appear only marginally conducive for additional development of this system. A small increase in organization could result in the formation of a short-lived tropical depression or storm later today while it moves westward to west-northwestward at 15 to 20 mph over the central tropical Atlantic.  After that time, upper-level winds are forecast to become less conducive for development. Formation chance through 48 hours...high...70 percent and formation chance through 5 days...high...70 percent.

Disturbance 4. Eastern Tropical Atlantic

A tropical wave has recently emerged off the west coast of Africa this morning. Environmental conditions appear conducive for some gradual development as the system moves generally west-northwestward over the eastern tropical Atlantic. Formation chance through 48 hours...low...near 0 percent and formation chance through 5 days...low...30 percent.
