2205 UTC Thu Apr 18 2024
Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.
Based on 1800 UTC surface analysis and satellite imagery through
2015 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A trough extends from Panama near 08N80W to 09N86W to 06N96W.
The ITCZ continues from 06N97W to 06N119W to 05N135W. Scattered
moderate to isolated strong convection is noted from 04N to 08N
between 116W and 130W. Scattered moderate convection is noted
from 04N to 07N between 90W and 96W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Moderate NW winds persist along the coast and offshore waters of
Baja California, between weak high pressure west of the area and
lower pressure over central Mexico. NW swell moving through the
regional waters is producing seas of 5 to 7 ft to the
Revillagigedo Islands while gradually subsiding. Gentle winds
and moderate seas persist elsewhere.
For the forecast, gentle to moderate winds winds and moderate
seas will persist through Sat. Looking ahead, fresh NW winds and
building swell will follow a weak cold front into the waters near
Guadalupe Island off Baja California Norte Sun and Mon.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR
Moderate N gap winds persist in the Gulf of Panama, with seas of
4 to 6 ft. Light to gentle winds and moderate seas of 3 to 5 ft
in SW swell are noted elsewhere.
For the forecast, mainly gentle breezes will persist across the
region into early next week. Wave heights will be mostly 4 to 6
ft primarily in SW swell, building to 5 to 7 ft off Ecuador Sat
night.
...REMAINDER OF THE AREA...
Broad ridging persists north of 20N, supporting moderate to
locally fresh trade winds across the tropical Pacific west of
120W. Combined seas are 8 to 10 ft in this area, in mainly
shorter- period easterly waves resulting from the trade wind
flow. Light to gentle breezes and moderate seas are evident
elsewhere.
For the forecast, wave heights will subside across the region
into the weekend, although an area of 8 ft seas will persist
from 08N to 12N west of 130W due to fresh trade winds and
lingering swell into early next week. A weak cold front will
enter the far NW waters Fri then dissipate over the weekend.
