NWS National Hurricane Center Miami FL
0405 UTC Tue Apr 6 2021

Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 140W. The following information is
based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0250 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

A surface trough extends from 09N79W to 06N90W to 06N96W. The ITCZ
begins near 05N96W and continues along 04N117W to 03N140W. Scattered
moderate isolated strong convection is from 04N to 09N between 82W
and 96W. Scattered moderate convection is from 01N to 07N W of 118W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A nearly stationary ridge sits west of Baja California and lower
pressure prevails over the SW CONUS. The pressure gradient from 
this pattern will continue to support fresh to locally strong NW 
winds over the Baja California Norte offshore waters, extending
to Cabo San Lazaro on Thu and continuing through Fri. Seas over 
the Baja California adjacent waters will range between 5 to 8 ft 
during this forecast period, with the highest seas N of Punta 
Eugenia. By Fri night and into the weekend, strong northerly 
winds will move into the offshores of Baja California Norte along
with NW swell forecast to support seas to 11 ft.

Light winds prevail across the Gulf of California. These winds
will increase moderate to fresh briefly in the southern Gulf of
California by Tue and diminish by Tue night. Light to gentle
winds will continue to prevail the rest of the week. 

In the Gulf of Tehuantepec, moderate to fresh northerly winds 
will continue over the Gulf of Tehuantepec through Tue. Otherwise,
moderate to fresh SW to W winds are forecast for Oaxaca adjacent
waters Fri and Sat. Elsewhere, light to gentle winds are 
expected to continue through Sat with seas to 6 ft in mixed 
southwest and northwest swell.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and 
WITHIN 750 NM OF ECUADOR...

Fresh to strong NE to E winds in the Gulf of Papagayo region 
will diminish to moderate to fresh on Tue and below moderate 
speeds on Wed. Moderate to fresh N to NE winds in and downstream 
of the Gulf of Panama will continue through Tue early in the 
evening. Light to gentle winds will prevail across the rest of 
the region through the forecast period with seas to 7 ft. 

REMAINDER OF THE AREA...

Surface ridging dominates the open forecast waters N of 18N W of
120W. Over the far NW forecast waters, moderate NW to W winds 
with seas to 9 ft are near a cold front that extends from 30N129W
to 20N140W. The front will transition to a stationary front and
will continue to weaken before dissipating on Tue. NW swell 
associated with the front will subside by Tue afternoon.

Elsewhere, the pressure gradient between the ridge to the north 
and the ITCZ will continue to support moderate to fresh trades 
from 05N to 20N W of 120W through tonight. Seas in this region 
will build to 8 ft in mixed SW and NW swell. Quiescent conditions
can be expected from Tue through the rest of the week across this
area.
