Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1548 UTC Mon May 4 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

A surface trough extends from 09N83W to 07N85W to 07N110W. The 
ITCZ extends from 07N110W to 08N120W to beyond 05N140W. Scattered
moderate to isolated strong convection from 05N to 08N between
82W and 90W, and from 04N to 10N between 97W and 117W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A weak ridge reaches from 1024 mb high pressure centered near 
30N131W through the Revillagigedo Islands. Fresh to strong NW 
winds off the coast off Baja California Norte along with seas of 
6 to 9 ft are a result of the pressure gradient between this 
ridge and low pressure trough over Baja California. Moderate to 
locally fresh winds are also funneling near Cabo San Lucas. Light
to gentle breezes prevail over elsewhere over the Mexico 
offshore waters. Seas are 4 to 6 ft in open waters. Moderate 
smoke due to agricultural fires may be limiting visibility across
the Gulf of Tehuantepec and off Chiapas.

The fresh winds and 6 to 9 ft seas will persist off Baja 
California, mainly north of Punta Eugenia, through tonight as 
the surface trough over the area deepens. NW swell will persist 
off Baja California Norte into late week. Farther south, smoke 
from agricultural fires may reduce visibility at times off the 
coast of Chiapas including the Gulf of Tehuantepec. Looking 
ahead, fresh to locally strong gap winds are likely to develop
Wed and Thu nights.

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

Fresh gap winds are occurring in the Gulf of Papagayo, with 
moderate gap winds taking place in the Gulf of Panama. Elsewhere
light to gentle winds prevail. Seas remain 4 to 6 ft through the
region. Moderate smoke covers the offshore waters off Guatemala,
El Salvador, and Nicaragua.

Gap winds will diminish through mid week, but nightly pulses of
moderate to fresh winds are possible in the Gulf of Papagayo.
Smoke from agricultural fires in Central America will continue to
reduce visibility at times in the waters off Guatemala, El 
Salvador, and Nicaragua. Some SW long period swell may begin to
approach the Galapagos Islands for the latter half of the week.

REMAINDER OF THE AREA...

A high pressure ridge north of 20N maintains moderate to fresh 
trades over the waters across the tropical waters west of 120W. 
Wave heights peak around to 8 ft from 10N to 15N west of 135W in
mixed NW and SE swell. Elsewhere, moderate to locally fresh 
trades are noted near the ITCZ west of 110W. Gentle winds 
generally prevail east of 110W. A weak cold front has stalled 
near 30N140W and will dissipate tonight. NW swell to 8 ft will 
accompany the front north of 25N and west of 135W. Southern 
Hemispheric long period SW swell is likely to move N of the 
equator for the latter half of the week.
