For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Near the Yucatan Peninsula:
A large and complex area of low pressure is expected to develop 
near the Yucatan Peninsula and the northwestern Caribbean Sea in 
a few days, partially related to the remnants of Hurricane Agatha 
from the eastern Pacific. This system is forecast to move slowly 
eastward or northeastward and gradual development is possible 
by the latter part of this week.  Regardless of development, 
locally heavy rainfall is likely across portions of southern 
Mexico, the Yucatan Peninsula, Guatemala, and Belize through 
the week.

DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), the center of Hurricane Agatha was located
near latitude 15.1 North, longitude 97.3 West.  Agatha is moving
toward the northeast near 6 mph (9 km/h), and this general motion is
expected to continue through Tuesday.  On the forecast track, the
center of Agatha will make landfall in the state of Oaxaca, Mexico,
this afternoon or this evening.

Maximum sustained winds remain near 110 mph (175 km/h) with higher
gusts.  Little change in strength is expected today before Agatha
reaches the coast of Oaxaca.  Rapid weakening is expected after
landfall, and Agatha is forecast to dissipate over southeastern
Mexico by late Tuesday.

Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).

The estimated minimum central pressure is 964 mb (28.47 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the hurricane warning
area and possible in the watch area by this afternoon.  Tropical 
storm conditions have begun along the coast of Oaxaca and will 
spread eastward within the warning area through the day.

STORM SURGE:  Storm surge is expected to produce extremely 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
currently expected:

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.

Mexican states of Veracruz, Tabasco and eastern portions of
Guerrero: 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 day or two.  These swells are
likely to cause life-threatening surf and rip current conditions.

Hurricane Season Preditions

A little more than a week away from the start of the Atlantic hurricane season, the National Oceanic and Atmospheric Administration released its outlook for the 2022 season, predicting an above-average number of named storms.

Forecasters from NOAA’s Climate Prediction Center are predicting 14 to 21 named storms, 6 to 10 hurricanes and 3 to 6 major hurricanes (Category 3 or higher on the Saffir-Simpson Hurricane Wind Scale). These numbers are greater than the 30-year averages (1991-2020) of 14 named storms, seven hurricanes and three major hurricanes.

This marks the 7th consecutive above-average season, according to NOAA administrator Rick Spinrad.

Tropical Weather Outlook

200 PM EDT Sun May 22 2022

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. North Central Gulf of Mexico:
An area of disorganized showers and thunderstorms is associated with 
a surface trough of low pressure over the north central Gulf of 
Mexico. Surface pressures remain high, and environmental conditions 
do not appear favorable for significant development before this 
system moves inland over the central Gulf Coast in a day or so. 
Regardless of development, the system could produce heavy rainfall 
and gusty winds over portions of the central Gulf Coast from 
southeastern Louisiana to the western Florida Panhandle. Additional 
information on the rainfall and flooding potential can be found in 
products issued by your local National Weather Service Forecast 
Office and Excessive Rainfall Outlooks issued by the Weather 
Prediction Center. 
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
