Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0630 UTC Thu May 7 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 0600 UTC surface analysis and satellite imagery through
0615 UTC.

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

A surface trough extends from 09N79W to 07W107W. The ITCZ 
extends from 07N107W to 06N140W. Scattered moderate convection 
is noted from 04N to 07N E of 82W and from 04N to 09N between 
109W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends from a 1030 mb surface high pressure offshore of
northern California through 30N132W to well W of Cabo San Lucas.
Moderate NW winds are present offshore Baja California Norte 
along with seas of 8 to 10 ft in NW swell. Gentle 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 through this evening, while 
winds diminish. Areas of moderate S to SE winds are expected to 
develop in the Gulf of California this afternoon through 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 today. High
pressure building in behind a cold front over the western Gulf of
Mexico will lead to near gale force northerly gap winds in the
Gulf of Tehuantepec through late tonight along with seas of 8 to
10 ft. Seas generated by the northerly gap winds will mix with 
longer period southerly swell reaching the area Fri. More strong
to near gale force gap winds are expected in the Gulf of 
Tehuantepec Sun through late Mon.

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

Moderate to fresh gap winds are occurring across the Papagayo 
region. 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 
will persist today.

Fresh gap winds will pulse to strong tonight in the Papagayo
region as high pressure builds north of the area. SW long period
swell will reach the Galapagos Islands this afternoon and prevail
through Fri night. This swell is forecast to reach 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 will continue west of
Guadalupe Island, north of 25N and east of 125W. 1030 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 late week, with seas diminishing below 8 
ft. Meanwhile Southern Hemispheric long period SW swell is
crossing the equator east of 125W and will bring 8 to 10 ft seas
south of 13N 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 and far southern Mexico.
