Mexico.

1. Eastern and Central Tropical Atlantic (AL98):
A broad low pressure system associated with a tropical wave located 
west of the Cabo Verde Islands continues to produce disorganized 
shower and thunderstorm activity. Environmental conditions appear 
favorable for gradual development of this system, and a tropical 
depression is likely to form in a few days while it moves westward 
to west-northwestward across the eastern and central tropical 
Atlantic.
* Formation chance through 48 hours...medium...60 percent. 
* Formation chance through 7 days...high...80 percent.

2. Central Subtropical Atlantic (AL99): 
A non-tropical area of low pressure is currently located several 
hundred miles to the northeast of Bermuda. The system is currently 
producing winds up to storm force, and environmental conditions 
could support the low developing some subtropical or tropical 
characteristics over the next several days as the system moves 
generally east-northeastward, remaining over the central Subtropical 
Atlantic. Additional information on this system, including storm 
warnings, can be found in High Seas Forecasts issued by the National 
Weather Service.
