HAZARDS AFFECTING LAND
STORM SURGE: A dangerous storm surge will raise water levels by
as much as 5 to 7 feet above normal tide levels near and to the
north of where Katia makes landfall. Near the coast, the surge will
be accompanied by large and destructive waves.
RAINFALL: Katia is expected to produce total rain accumulations of
10 to 15 inches over northern Veracruz, eastern Hidalgo, and
Puebla. Katia is also expected to produce total rain accumulations
of 2 to 5 inches over southern Tamaulipas, eastern San Luis Potosi,
western Hidalgo, eastern Queretaro, and southern Veracruz through
Saturday evening. Isolated maximum amounts of 25 inches are
possible in northern Veracruz, eastern Hidalgo, Puebla, and San
Luis Potosi. This rainfall may cause life-threatening flash floods
and mudslides, especially in areas of mountainous terrain.
WIND: Hurricane conditions are expected within portions of the
hurricane warning area by tonight or early Saturday, with tropical
storm conditions expected within the tropical storm warning areas by
SURF: Swells generated by Katia will continue to affect portions of
