Tropical Weather Discussion 
NWS National Hurricane Center Miami FL
0405 UTC THU JUN 09 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
0230 UTC.
  
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...         

The monsoon trough extends from 10N110W to 10N120W to low
pressure near 12N129W to 09N138W. The ITCZ extends from 09N138W
to beyond 08N140W. Scattered moderate convection was noted
within 120 NM S of the monsoon trough between 122W and 131W.
 
...DISCUSSION...   

Even though Tropical Depression One-E has dissipated, SW monsoon
flow continues over the eastern North Pacific continuing the
potential for heavy rainfall over the southern facing slopes of
Central America. 

High pressure of 1019 mb centered over the northern waters near
28N130W extends a ridge se to near 19N112W. The pressure
gradient between the area of high pressure and the area of low
pressure embedded in the monsoon trough near 12N129W is
supporting fresh to strong winds over the northern quadrant of
the low and seas to 8 ft. The area of low pressure will weaken
over the next 24 hours and winds and seas will diminish below
advisory criteria by Thursday morning. Outside this tighter
pressure gradient...the pressure gradient between the weak area
of high pressure and the monsoon trough is supporting gentle to
moderate winds N of the monsoon trough with seas in the 3 to 5
ft range. High pressure will slowly build in across the northern
waters and tighten the pressure gradient to help support
moderate to fresh trades N of the monsoon trough with seas
building to 5 to 7 ft by Friday. 

The pressure gradient between the ridge and lower pressure over
the Gulf of California is supporting moderate NW winds off the
coast of Baja California with seas in the 4-5 ft range. SW
monsoon flow prevails to the E of 100W with light to moderate
winds prevailing. Active weather is expected to continue over
the eastern waters during the next couple of days as this moist
monsoonal flow persists.
