Tropical Weather Discussion...Corrected NWS National Hurricane
Center Miami FL 1605 UTC Sat Jun 22 2024

Corrected Remainder of the Area section

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1545 UTC.

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

The monsoon trough extends from 15N95W to 10N115W to 09N130W.
The ITCZ extends from 09N130W to beyond 06N140W. Scattered
moderate convection is seen within 180 nm south of the trough
between 97W and 101W, within 60 nm south of the trough between
115W and 120W and within 30 nm of the ITCZ between 136W and 140W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

An overnight altimeter satellite pass indicated seas of 8 to 10
ft offshore of Oaxaca in southern Mexico, beyond 90 nm from the
coast. These combined seas are mostly due to long-period
southwest swell lingering from southwest fresh to strong winds
of the past few days. Deep-layer moisture remains abundant over
the area, supporting scattered showers and thunderstorms along
the coasts of the states of Guerrero and northern Michoacan.
This activity reaches offshore for about 120 nm.

Scattered moderate to isolated strong that moved offshore
Mexican coast during the overnight hours is weakening as it
moves northwestward just offshore the coast between 17N and
Manzanillo extending offshore for about 120 nm.

For the forecast, winds and seas will continue to improve today
off the southern Mexico offshore waters. To the north, fresh
northwest winds and rough seas are expected over the Baja
California offshore waters through tonight. Conditions across
the Mexico offshore waters will improve through the early part
of next week.

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

The broad low pressure over northern Central America has
weakened and shifted northward, allowing winds and seas to
diminish across the region. Seas to 8 ft persist in the offshore
waters of Guatemala beyond 90 nm, associated with lingering SW
swell caused by persistent fresh to strong SW winds. Elsewhere,
gentle to moderate winds and mostly moderate combined seas
persists.

For the forecast, seas to 8 ft will linger off Guatemala today,
then subside. Gentle to moderate winds and slight to moderate
wave heights will persist elsewhere across the region through
the early part of next week.

...REMAINDER OF THE AREA...Corrected

A broad surface ridge extends from strong high pressure of 1029
mb that is located well NW of the area near 35N154W,
southeastward to the Baja California offshore waters. The
associated gradient is supporting generally gentle to moderate
north to northeast winds west of about 110W, except for slightly
higher fresh northeast winds north of 22N west of 137W as seen
in overnight ASCAT satellite data passes over that part of the
area. Seas with these winds are in the range of 4 to 6 ft,
except for slightly higher seas of 5 to 7 ft north of 22N west
of 137W. Gentle to moderate east to southeast winds are south of
04N between 83W and 100W, and mostly gently south to southwest
winds are elsewhere south of the monsoon trough and mostly
gentle east to southeast are south of the ITCZ. Seas with these
winds are 5 to 7 ft, except for seas of 7 to 9 ft in long-period
southwest swell south of the monsoon trough to 07N between 95W
and 107W.

For the forecast, monsoonal winds and seas east of 110W and
north of 05N will gradually decrease today. Otherwise, little
overall changes are expected through early next week.
