THIS AREA OF HIGH PRESSURE AND A TROUGH OVER THE GULF OF
CALIFORNIA IS SUPPORTING GENTLE TO LOCALLY MODERATE WINDS WEST
OF THE BAJA CALIFORNIA PENINSULA. THE PRESSURE GRADIENT BETWEEN
HIGH PRESSURE OVER THE EASTERN SLOPES OF MEXICO AND THE
EQUATORIAL TROUGH IS SUPPORTING FRESH TO STRONG WINDS IN THE
GULF OF TEHUANTEPEC. LIGHT TO GENTLE WINDS PREVAIL ELSEWHERE.

HIGH PRESSURE PREVAILS OVER THE WATERS N OF 20N. THE PRESSURE
GRADIENT BETWEEN THE AREA OF HIGH PRESSURE AND LOWER PRESSURE IN
THE VICINITY OF THE ITCZ IS SUPPORTING MODERATE TO FRESH TRADE
WINDS FROM 05N TO 15N BETWEEN 120W AND 140W, WHERE SEAS ARE IN
