Tropical Weather Discussion 
NWS National Hurricane Center Miami FL 
0405 UTC Sun Jul 10 2016

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
0200 UTC.

Tropical Storm Celia centered near 14.5N 118.9W at 0300 UTC Jul
10 moving west at 10 kt. Maximum sustained winds are 55 kt with
gusts to 65 kt. Estimated minimum central pressure is 994 mb.
Numerous moderate to strong convection within 90 nm S and 30 nm
N of the center. Celia is expected to intensify as it moves west
and become a hurricane tonight. See latest NHC forecast advisory
under AWIPS/WMO headers MIATCMEP4/WTPZ24 KNHC for more details.

Tropical Storm Blas centered near 21.2N 134.5W at 0300 UTC Jul
10 moving west at 10 kt. Maximum sustained winds are 35 kt with
gusts to 45 kt. Estimated minimum central pressure is 1003 mb.
Isolated moderate convection is within 45 nm of the center. Blas
is expected to continue to weaken during the next 12-24 hours
and become a remnant low Sun. See latest NHC forecast advisory
under AWIPS/WMO headers MIATCMEP3/WTPZ23 KNHC for more details.

...Tropical Waves...

A tropical wave N of 08N along 94W is moving west at 20 kt.
Isolated convection is within 90 nm E of the wave axis. 

..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

A monsoon trough extends from 08N76W to 11N111W. Scattered
moderate convection is from 08N to 13N between 94W-114W.

...DISCUSSION...   

A ridge axis extending from high pressure NW of the area
prevails over northern waters generally N of 23N W of 115W.
Gentle to moderate winds are occurring N of 23N, with large
mixed swell generated from Tropical Storm Blas propagating
northward into northern waters west of 125W. Seas associated
with Blas will gradually subside through Monday as the cyclone
weakens and moves west of 140W. However, expect seas generated
by TS Celia to steadily build and expand outward as the cyclone
intensifies and the central core broadens. These systems have
disrupted the convergence zone west of 110W. Seas in southern
waters are combined swell around 5-6 ft, from the tropical
cyclones to the north, and cross-equatorial swell to the south. 

Elsewhere, fresh winds will continue to pulse near the Gulf of
Papagayo the next several days. NW swell generated by strong to
gale force winds off the California coast will sweep south of
30N Mon morning with max seas building to 9-10 ft Mon afternoon.
