Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Aug 22 2017
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...
Hurricane Kenneth is centered near 20.0N 132.5W at 0900 UTC,
moving NW at 9 knots. The estimated minimum central pressure is
978 mb. Maximum sustained winds are 80 kt with gusts to 100 kt.
Numerous moderate scattered strong convection is within 90 nm of
the center. Kenneth is forecast to weaken steadily through Thu.
Please refer to the National Hurricane Center Forecast Advisory
under WMO/AWIPS headers WTPZ23 KNHC/MIATCMEP3, and the High Seas
Forecast under WMO/AWIPS headers FZPN03 KNHC/MIAHSFEP2 for more
information.
..TROPICAL WAVES...
A tropical wave is along 98W from 18N southward to 10N, moving
westward at 15 to 20 knots. No significant convection is
associated with this wave.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends westward from 08N78W to 11N100W to
10N119W to 07N126W. Widely scattered moderate convection is
within 120 nm of the axis between 112W and 127W.
...DISCUSSION...
OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A surface trough will prevail across the Gulf of California
through the end of the week with a weak surface low developing
at times along the trough north of 29N. The pressure gradient
between this elongated area of low pressure and surface ridging
W of the area will allow moderate NW winds off Baja California
through early Friday, then decreasing to a gentle breeze. Seas
will remain between 3 and 5 ft.
Gulf of Tehuantepec: Fresh northerly winds will funnel into the
Gulf of Tehuantepec through early Wed with seas to 7-8 ft.
OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND
WITHIN 750 NM OF ECUADOR...
Light and variable winds are expected N of the monsoon trough
through Friday while moderate to locally fresh WSW winds are
expected S of the monsoon trough axis, with 4 to 6 ft seas.
REMAINDER OF THE AREA...
Low pressure west of northern Baja California near 31N126W will
weaken to a trough later today, then persist over the waters W
of northern Baja into Thu. High pressure centered near 35N142W
will tighten the pressure gradient over NW waters as weakening
tropical cyclone Kenneth moves northward, and help increase seas
over a large portion of the area N of 25N and W of 135W. N swell
generated by strong northerly winds N of the area has increased
seas to 8-9 ft north of 28N between 127W and 134W. Conditions
will merge with swell generated by Kenneth. Moderate to locally
fresh anticyclonic flow is forecast elsewhere N of the monsoon
trough and W of 120W.
