DISCUSSION AND OUTLOOK
At 100 PM CDT (1800 UTC), the center of Hurricane Agatha was located
near latitude 14.2 North, longitude 99.0 West. Agatha is drifting
toward the north near 2 mph (4 km/h). A turn toward the
northeast is expected later today, with a motion toward the
northeast continuing through Monday night. On the forecast track,
the center of Agatha will approach the southern coast of Mexico
later today and tonight and make landfall there on Monday.
Agatha has continued to strengthen. Maximum sustained winds have
increased to near 90 mph (150 km/h) with higher gusts. Additional
strengthening is expected during the next 12 to 24 hours and Agatha
is forecast to be near major hurricane strength when it reaches the
coast of southern Mexico on Monday.
Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 80
miles (130 km).
The estimated minimum central pressure is 978 mb (28.88 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected in the hurricane warning
area and possible in the watch area on Monday, with tropical storm
conditions beginning tonight or early Monday.
STORM SURGE: Storm surge is expected to produce dangerous coastal
flooding in areas of onshore winds near and to the east of where the
center of Agatha makes landfall. Near the coast, the surge will be
accompanied by large and destructive waves.
RAINFALL: Agatha will produce heavy rains over portions of southern
Mexico through Tuesday night. The following rainfall amounts are
Mexican state of Oaxaca: 10 to 16 inches, with isolated maximum
amounts of 20 inches possible. Life-threatening flash flooding and
mudslides may occur.
Mexican state of Chiapas: 5 to 10 inches, with isolated maximum
amounts of 15 inches possible. Life-threatening flash flooding and
mudslides may occur.
Eastern portions of the Mexican state of Guerrero: 2 to 6 inches,
with isolated maximum amounts of 10 inches possible.
Life-threatening flash flooding and mudslides may occur.
Mexican states of VeraCruz and Tabasco: 2 to 4 inches, with isolated
maximum amounts of 6 inches possible.
SURF: Large swells generated by Agatha will affect the coast of
southern Mexico during the next few days. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
