The National Hurricane Center is issuing advisories on Hurricane 
Sam, located several hundred miles east of Lesser Antilles.

1. Showers and thunderstorms have become a little better organized 
today in association with a surface trough (the remnants of 
Peter) located several hundred miles southeast of Bermuda. 
Upper-level winds are marginally conducive for further
development, and Peter could become a tropical depression again 
during the next couple of days while it moves northeastward at 
about 10 mph. By midweek, environmental conditions are expected to 
become unfavorable for further development. 
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

2. A tropical wave is expected to move off the west coast of Africa on 
Monday.  Upper-level winds are forecast to be conducive for gradual 
development thereafter, and a tropical depression is likely to 
form in a few days while the system moves westward to west- 
northwestward at 10 to 15 mph over the far eastern tropical 
Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...high...70 percent.

3. A broad area of low pressure appears to be be forming several 
hundred miles southwest of the Cabo Verde Islands.  Environmental
