Mexico tonight and on Tuesday after Agatha moves inland.

WIND: Hurricane conditions are expected in the hurricane warning
area and possible in the watch area by this afternoon or this
evening, with tropical storm conditions beginning this morning.
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
Mexican state of Oaxaca: 10 to 16 inches, with isolated maximum
amounts of 20 inches possible. Life-threatening flash flooding and
