For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Hurricane
Irma, located a couple hundred miles east of the Leeward Islands.
1. Showers and thunderstorms associated with an area of low pressure
located about 1000 miles west-southwest of the Cabo Verde Islands
are gradually becoming better organized. Conditions appear
conducive for continued development of this system. There is a
high likelihood that a tropical depression or tropical storm will
form within the next day or two while the disturbance moves
west-northwestward at 10 to 15 mph over the tropical Atlantic Ocean.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.
2. A trough of low pressure located over the southwestern Gulf of
Mexico is producing numerous showers and thunderstorms.
Environmental conditions are conducive for gradual development, and
this system is likely to become a tropical depression during the
next couple of days while it meanders over the southwestern Gulf of
Mexico. Regardless of development, heavy rains associated with this
disturbance are likely over portions of eastern Mexico during the
remainder of the week.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.
