200 AM EDT Mon Aug 6 2018

For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

1. A non-tropical, surface low pressure system centered about 1200
miles southwest of the Azores is interacting with a broad
upper-level low. Although thunderstorm activity has increased near
and to the east of the low-level center, environmental conditions
are expected to be only marginally conducive for the low to acquire
subtropical or tropical characteristics while it moves little over
the next day or so. By Monday afternoon, the low is expected to move
toward the north or north-northeast and continue that motion through
Tuesday. Additional information on this system can be found in High
Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours…low…20 percent.
* Formation chance through 5 days…low…20 percent.

High Seas Forecasts issued by the National Weather Service can be
found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and
