Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Dexter, located over the northwestern Atlantic Ocean.

1. Off the Southeastern United States:
A weak surface trough currently located several hundred miles off
the coast of the southeastern United States is expected to form an
area of low pressure in a day or so. Thereafter, environmental
conditions appear favorable for gradual development of this system,
and a tropical depression could form by the latter portion of this
week or weekend as as the low initially moves slowly westward, but
turns more northward by this weekend.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.

2. Central Tropical Atlantic:
A tropical wave over the far eastern tropical Atlantic is currently
producing disorganized shower and thunderstorm activity, primarily
to the southwest of the wave axis. Environmental conditions are
forecast to be conducive for gradual development during the next few
days, and a tropical depression could form late this week or over
the weekend as the system moves generally west-northwestward across
the central tropical or subtropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.
