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 extremely dangerous
coastal flooding in areas of onshore winds near and to the east of

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.

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,
