1. Shower and thunderstorm activity associated with a low pressure
system located several hundred miles southwest of the Azores has
increased and become better organized during the past several hours.
Satellite-derived wind data earlier this morning suggested that the
system had not yet become distinct from a frontal boundary in the
area, however, it will likely become non-frontal soon. The satellite
data also indicated that the system is already producing gale-force
winds. Additional development is expected, and a tropical or
subtropical storm will likely form during the next day or two while
the system moves eastward or east-northeastward over the
northeastern Atlantic Ocean.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.
1. Shower activity associated with a non-tropical low pressure system
located several hundred miles southwest of the Azores is showing
some signs of organization. This system will likely gradually
acquire subtropical or tropical characteristics this week, and a
tropical or subtropical storm could develop within a few days while
this system moves eastward or east-northeastward over the
northeastern Atlantic Ocean.
* Formation chance through 48 hours...medum...40 percent.
* Formation chance through 5 days...medium...60 percent.
