ARC+ Weather forecast 12/11/2015

All times in GMT/UTC

PREPARED: November 12 05:37

Synopsis: Good morning. A thermal trough extends along much of the W African coast from Senegal N to/along W Sahara. This will persist with a very slow strengthening thru the 13/11.

Moderate ridging extends from near Madeira S to the Cape Verde Islands and this will change little thru the 13/11.

A trough of low pressure extending from 45N/45W extending NE towards 50N/10W. This trough will move NE while weakening thru the 14/11.

Conclusion: Enhanced NE will be found in the N parts of Grids BB and AA today as a trough of low pressure departs to the N, with gusts reaching 30kts and gradually easing thru the morning hours. Otherwise, N will become enhanced starting tomorrow in E portions of Grids GG and MM along the African coast due to the interaction between the thermal trough of low pressure and high pressure ridging. Winds and swells will tend toward the higher end of the ranges in those sections E of longitude 20W.
