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

The National Hurricane Center is issuing advisories on Tropical 
Storm Kate, located over the central tropical Atlantic.

The Weather Prediction Center is issuing Public Advisories on 
Tropical Depression Ida, located over northeastern Mississippi.

1. A well-defined low pressure system is located over the far eastern 
tropical Atlantic, a couple of hundred miles west-southwest of the 
coast of Guinea.  Associated showers and thunderstorms continue to 
show signs of organization, and environmental conditions are 
conducive for additional development of this system.  A tropical 
depression is likely to form during the next day or so while the low 
moves westward to west-northwestward at 10 to 15 mph. 
* Formation chance through 48 hours...high..90 percent.
* Formation chance through 5 days...high...90 percent.

2. A broad area of low pressure is forecast to develop over the 
southwestern Caribbean Sea during the next couple of days.  Some 
slow development of this system is possible by the end of the week, 
if the system remains over water.  This system is expected to move 
gradually west-northwestward or northwestward at 5 to 10 mph toward 
Central America. 
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...low...20 percent.
