1. Shower activity associated with a non-tropical area of low pressure,
located several hundred miles south-southwest of Cape Race,
Newfoundland, has increased a little since yesterday.  However,
environmental conditions are only marginally conducive, and little
additional development is expected while the low moves little over
the next day or so.  On Friday, the low is expected to accelerate
northeastward and open up into a trough of low pressure to the
south of Atlantic Canada.  Additional information on this system
can be found in High Seas Forecasts issued by the National Weather
Service.  
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.

1. Shower activity associated with a non-tropical area of low
pressure located several hundred miles south-southwest of
Newfoundland is becoming less organized, and recent satellite wind
data indicate that the circulation is weakening.  The low is
expected to degenerate to a trough later today south of
Newfoundland, and its chances of tropical cyclone formation have
diminished.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.
