Two tropical disturbances expected to strengthen Monday

Two areas of tropical weather worth watching.

We're tracking 2 tropical systems, both are expected to become stronger on Monday. One in the Western Caribbean and another about 2300 miles to the Southeast of West Palm Beach. Both systems bear watching. Currently, neither system poses any direct threat to South Florida.

Here is the very latest from the National Hurricane Center:

1. Showers and thunderstorms associated with a tropical wave about 550 miles east-southeast of the southern Windward Islands have become a little better organized since yesterday.

Some additional development of this system is possible during the next couple of days before environmental conditions become less favorable for tropical cyclone formation. This system is forecast to move to the west at near 23 mph toward the Windward Islands and northeastern South America during the next two days, and interests in these areas should monitor its progress.

Regardless of development, locally heavy rains and gusty winds are likely to spread over portions of the Windward Islands Monday night and Tuesday.

An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate this system on Monday, if necessary.

* Formation chance through 48 hours...high...90 percent.

* Formation chance through 5 days...high...90 percent.

2. Surface observations and satellite data indicate that a broad low pressure area is centered near the east coast of the Yucatan Peninsula.

This system is producing a large area of showers and thunderstorms along with winds to gale force several hundred miles to the east and northeast of the center. However, the low lacks a well-defined center of circulation, and the Hurricane Hunter mission scheduled for this afternoon has been canceled.

Gradual development is expected while the low moves slowly north-northwestward across the Yucatan Peninsula through tonight, and then over the southern or central Gulf of Mexico on Monday and Tuesday, where a tropical or subtropical cyclone is likely to form.

Regardless of development, heavy rains are expected over portions of Central America, the Yucatan Peninsula, Jamaica, the Cayman Islands, and western Cuba during the next several days. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate this system on Monday, if necessary.

For more information on this system, please see the High Seas Forecast issued by the Tropical Analysis and Forecast Branch.

* Formation chance through 48 hours...high...90 percent.

* Formation chance through 5 days...high...90 percent.
