Tropical Weather Discussion
NWS National Hurricane Center Miami FL
930 UTC Fri Jul 27 2018
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 FEATURES...
Newly formed Tropical Storm Gilma centered near 14.4N 126.7W at
27/0900 UTC or 1690 nm E of South Point Hawaii moving WNW at 14
kt. Estimated minimum central pressure is 1006 mb. Maximum sustained
wind speed is 35 kt with gusts to 45 kt. Scattered moderate to
strong convection is currently observed within 90 nm of the
center of the storm. See latest NHC forecast/advisory under
AWIPS/WMO headers MIATCPEP3/WTPZ33 KNHC for more details.
Tropical Depression Nine-E centered near 10.7N 137.7W at 27/0900
UTC or 1140 nm ESE of Hilo Hawaii moving W at 10 kt. Estimated
minimum central pressure is 1008 mb. Maximum sustained wind
speed is 30 kt with gusts to 40 kt. Scattered moderate to
isolated strong convection is observed within 150 nm in the
west quadrant of the center of the depression. See latest NHC
forecast/advisory under AWIPS/WMO headers MIATCPEP4/WTPZ34 KNHC
for more details.
...TROPICAL WAVES...
A tropical wave extends along 95W north of 05N, moving west at 15
to 20 kt. Scattered moderate to strong convection is observed
where the tropical wave axis intersects with the Gulf of
Tehuantepec. Scattered moderate convection is noted where the
tropical wave axis is interacting with the monsoon trough, from
05N to 08N between 90W and 95W.
A tropical wave extends along 114W from 09N to 15N, moving west
at 10 to 15 kt. Scattered moderate convection is noted from 10N
to 15N between 110W and 115W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from 08.5N78.5W to 09N84W to 08N100W
to 13N120W, where it loses identity. Scattered moderate
convection is noted from 05N to 08N between 90W and 95W.
...DISCUSSION...
OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A broad N-NW to S-SE orientated trough will persist from the
northern Gulf of California through Baja California Norte to
24N120W through Sun. The associated weak pressure pattern will
maintain light to gentle breezes and moderate seas across the
region into next week. Mainly nighttime scattered showers and
thunderstorms may be active off the coast between Puerto Angel
and Manzanillo through Sat as a tropical wave pass westward
through the region enhancing overnight drainage convection.
OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA,
COLOMBIA, AND WITHIN 750 NM OF ECUADOR...
Gulf of Papagayo: Fresh easterly flow is expected through early
Fri afternoon followed by mostly moderate E flow through the
weekend.
Gentle to occasionally moderate E winds are forecast elsewhere N
of the monsoon trough which is meandering between 08N and 10N.
Moderate to locally fresh southerly winds are forecast S of the
monsoon trough for the next several days accompanied by 5 to 7
ft seas.
REMAINDER OF THE AREA...
See the special features section for information on Tropical
Storm Gilma and Tropical Depression 9-E, along the tropical
waves section for details on a wave along 95W. Otherwise,
surface ridging will persist north of 20N surrounded by moderate
to locally fresh anticyclonic winds and 5 to 7 ft seas. Moderate
to locally fresh southerly forecast elsewhere S of the monsoon
trough or roughly 10N for the next several days.
