NWS National Hurricane Center Miami FL
1005 UTC Wed Jul 24 2019

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 
0900 UTC. 

...SPECIAL FEATURE...

Tropical Depression Dalila centered near 19.8N 118.8W at 24/0900 
UTC moving NW at 5 kt. Estimated minimum central pressure is 
1007 mb. Maximum sustained wind speed is 30 kt with gusts to 40 
kt. Scattered moderate isolated strong convection is within 120 
nm Se of the center. Dalila will continue to weaken as it moves 
to 20.4N 119.5W this afternoon, then become a remnant low Thu 
morning. See the latest NHC forecast/advisory under AWIPS/WMO 
headers MIATCMEP5/WTPZ25 KNHC for more details. 

...TROPICAL WAVES...

A tropical wave is along 98W north of 03N, moving W around 15 
kt. Isolated convection is noted near the wave axis.  

A tropical wave is along 107W from 03N to 18N, moving W around 
10 kt. Scattered moderate convection is observed along the wave 
axis from 10N to 18N. 

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

The monsoon trough extends from 08N77W to 11N100W to 08N113W, 
then continues SW of Dalila from 14N121W to 10N133W. Aside from 
convection associated with tropical waves and Dalila, Scattered 
moderate to strong convection is noted from 04N to 10N between 
81W and 90W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A weak ridge will dominate the offshore forecast waters west of 
Baja California through Fri. Light to gentle southerly winds are 
expected across the Gulf of California during the next several 
days. Northerly winds will increase to a fresh to strong breeze 
across the Tehuantepec region by late Thu night. This gap wind 
event is expected to persist through Sun.

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

Moderate to locally fresh S to SW winds south of the monsoon 
trough will generally maintain seas to 7 ft off the coasts of 
Panama and Colombia through Fri. Seas will also build to 8-9 ft 
near the equator Thu and Fri as long-period S swell moves into 
the region. Fresh to strong gap winds will develop in the Gulf 
of Papagayo on Thu in the wake of a passing tropical wave. 

REMAINDER OF THE AREA... 

A ridge dominates most of the forecast waters N of 15N W of 
120W. Recent scatterometer and altimeter data indicate moderate 
to fresh trade winds from 16N to 21N west of 135W with seas to 8 
ft. Long period cross-equatorial southerly swell will build seas 
to around 8 ft along the Equator S of Galapagos tonight and Thu.
