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

1. A complex, non-tropical low pressure system is forecast to develop
over the southwestern Atlantic by Saturday. The system is expected
to move eastward to east-northeastward over the western and central
Atlantic through the middle of next week and could acquire some
subtropical characteristics during that time. Regardless of any
subtropical development, winds to gale force are expected over
portions of the western Atlantic during the next couple of days and
are possible over the central Atlantic by early next week.
Additional information can be found in High Seas Forecasts issued by
the National Weather Service. Interests in Bermuda should monitor
the progress of this system.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…low…30 percent.

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

Atlantic satellite image:

The Global Infrared Satellite image shows clouds by their temperature. Red and blue areas indicate cold (high) cloud tops. Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light, but shorter than that of terahertz radiation and microwaves. Weather satellites equipped with scanning radiometers produce thermal or infrared images which can then enable a trained analyst to determine cloud heights and types, to calculate land and surface water temperatures, and to locate ocean surface features.
