Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed May 6 2020

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 1800 UTC surface analysis and satellite imagery through
2100 UTC.

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

A surface trough extends from 10N75W TO 07.5N88W TO 07N110W. The
ITCZ extends from 07N110W TO 06.5N140W. Scattered strong
convection is noted from 03.5N TO 07.5N east OF 82W to coast of
Colombia. Scattered moderate isolated strong convection is noted
from 07N TO 12N between 87W AND 107W. Scattered moderate to 
strong convection is noted from 04.5N TO 09.5N between 116W AND 
140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends from a 1034 mb surface high pressure offshore of
northern California through 30N132W to near the Revillagigedo 
Islands. Moderate to fresh NW winds continue to offshore of Baja
California Norte, where seas are 8 to 10 ft in NW to N swell. 
Gentle to moderate winds and 5 to 7 ft seas are noted elsewhere. 
Northerly gales well offshore of southern California continue to
produce NW swell, that will persist off Baja California Norte 
into Thu night, while winds gradually diminish by Thu. Areas of  
moderate S to SE winds are expected to develop in the Gulf of 
California Thu night and Fri.

Gentle to moderate westerly breezes and 3 to 5 ft seas persist 
across the Mexican offshore waters south of 20N. Smoke from 
agricultural fires is expected to impact visibility near the 
shore, especially offshore Chiapas and Oaxaca, through Thu
morning. A late season cold front moving through the Gulf of 
Mexico will deliver near gale force gap winds across the Gulf of 
Tehuantepec late tonight and again Thu night, with seas building
to 10-11 ft. Seas generated by the northerly gap winds will mix 
with longer period southerly swell reaching the area late Thu. 
Another gap wind event is expected to develop across the Gulf of
Tehuantepec Sun.

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

Moderate gap winds are occurring across the Papagayo region this
afternoon. Elsewhere light to gentle winds prevail. Seas are 4 
to 6 ft through the region. Agricultural fires across Central
America are producing areas of smoke and reduced visibilities
across the nearshore waters from Tehuantepec to near the Gulf of
Fonseca this afternoon and will persist through Thu morning.

Fresh gap winds will pulse tonight across the Papagayo region, 
before increasing to strong Thu night as high pressure builds 
north of the area. SW long period swell will reach the Galapagos 
Islands Thu and Fri, and may reach some waters off Central 
America Fri night into the weekend.

REMAINDER OF THE AREA...

Northerly swell associated with strong to gale force northerly 
winds off the coast of southern California has moved into the 
waters west of Guadalupe Island, north of 25N and east of 125W. 
1034 mb high pressure centered offshore of northern California is
supporting moderate to fresh trade winds farther south into the 
deep tropics, where seas are 7 to 9 ft in a mix of NW swell and
tradewind seas. Seas are 6 to 7 ft elsewhere. The swell is 
expected to taper off into late week, with seas diminishing below
8 ft Thu night. Meanwhile Southern Hemispheric long period SW 
swell will move across the equator east of 125W this evening, 
bringing 8 to 10 ft seas south of 11N and east of 125W by late 
Fri. This swell will subside across the tropics below 8 ft Sat 
evening as it propagates toward Central America.
