10% chance in 48 hours / 10% chance in 5 days

Thunderstorm activity associated with an elongated area of low pressure located over the far southwestern portion of the eastern North Pacific remains disorganized. Some slow development of this system is possible during the next day or two while it remains nearly stationary. Further development is unlikely after that time as the system interacts with and is possibly absorbed by Kiko. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent.

0% chance in 48 hours / 0% chance in 5 days

An area of low pressure could form south of the southern coast of Mexico in a day or two. However, development into a tropical cyclone during the next five days appears unlikely. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...near 0 percent.

Hurricane JERRY

10% chance in 48 hours / 30% chance in 5 days

A tropical wave located over the central tropical Atlantic is producing a large area of disorganized cloudiness and showers. The wave is expected to move quickly westward at about 20 mph during the next few days, and some development is possible while it approaches and moves across the Windward Islands this weekend. Upper-level winds appear less conducive for development once the wave moves over the eastern Caribbean Sea early next week. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...30 percent.

10% chance in 48 hours / 10% chance in 5 days

A broad area of low pressure located over the central Caribbean Sea just south of Hispaniola is producing disorganized showers and thunderstorms to the east and northeast of its center of circulation. Upper-level winds are not conducive for significant development of this system while it moves slowly west-northwestward at about 5 mph. Regardless of development, locally heavy rainfall is possible over portions of the Greater Antilles during the next few days. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent.

0% chance in 48 hours / 50% chance in 5 days

A tropical wave is forecast to move off the west coast of Africa this weekend. Environmental conditions are expected to be conducive for development, and a tropical depression could form early next week while the wave moves westward over the eastern tropical Atlantic. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...medium...50 percent.
