HURRICANE PATRICIA:LARGEST STORM OF 2015 EASTERN PACIFIC HURRICANE SEASON OCTOBER 23, 2015 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA
PATRICIA: A CAT 5 STORM HEADS FOR LANDFALL IN MEXICO A RECORD STORM WITH WINDS OF 320-400 kph affecting Colima, Jalisco Nayarit, and states in center of Mexico
FROM A TROPICAL STORM TO A CAT 5 IN LESS THAN 24 HOURS A HUGE RAINMAKER BIG STORM SURGE
PREPARATION BEGINS • Residents of a stretch of Mexico's Pacific Coast dotted with resorts and fishing villages boarded up homes and bought supplies ahead of Friday's arrival of Hurricane Patricia, the strongest storm ever recorded in the Western hemisphere.
JAILSCO • Those on the coast will be in the most danger, especially people living in the state of Jalisco, which has a population of more than 7.3 million
EVACUATIONS UNDERWAY • Tens of thousands of people are being evacuated from Mexico's Pacific coast in anticipation of landfall later today (Friday—Oct. 23rd)
FLOOD WARNINGS IN TEXAS • The US National Weather Service placed large parts of Texas that are home to more than 10 million people under a flash flood watch on Friday as storms were expected to drop as much as 40 cm (15 inches) or more of rain throughout the weekend.
HURRICANES Planet Earth’s atmospheric-hydrospheric-lithospheric interactions create TROPICAL STORMS & HURRICANES

POTENTIAL DISASTER AGENTS AND RISK FROM TROPICAL STORMS AND HURRICANES LIKE PATRICIA
POTENTIAL DISASTER AGENTS (AKA HAZARDS) OF A HURRICANE • WIND FIELD [CAT 1 (55 mph) TO CAT 5+ (155 mph or greater)] • DEBRIS • STORM SURGE/FLOODS • HEAVY PRECIPITATION/FLOODS • LANDSLIDES (MUDFLOWS) • COSTAL EROSION
HIGH POTENTIAL LOSS EXPOSURES IN A HURRICANE Entire communities; People, property, infra-structure, business enterprise, government centers, crops, wildlife, and natural resources.
NATURAL HAZARDS THAT HAVE CAUSED DISASTERS FLOODS GOAL: PROTECT PEOPLE AND COMMUNITIES HURRICANES EARTHQUAKES/TSUNAMIS HIGH BENEFIT/COST FROM BECOMING DISASTER NRESILIENT VOLCANOES WILDFIRES GLOBAL CLIMATE CHANGE

A DISASTER is --- --- the set of failures that overwhelm the capability of a community torespond without external help when three continuums: 1) people, 2) community (i.e., a set of habitats, livelihoods, and social constructs), and 3) complex events (e.g., windstorms, floods,…) intersect at a point in space and time.
Disasters are caused by single- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.
THE REASONS ARE . . . • When it does happen, the functions of the community’s buildings and infrastructure can be LOST.
THE REASONS ARE . . . • The community is UN-PREPARED for what will likely happen, not to mention the low-probability of occurrence—high-probability of adverse consequences event.
THE REASONS ARE . . . • The community has NODISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.
THE REASONS ARE . . . • The community LACKS THE CAPACITY TO RESPOND in a timely and effective manner to the full spectrum of expected and unexpected emergency situations.
THE REASONS ARE . . . • The community is INEFFICIENT during recovery and reconstruction because it HAS NOT LEARNED from either the current experience or the cumulative prior experiences.
THE ALTERNATIVE TO A HURRICANE DISASTER ISHURRICANE DISASTER RESILIENCE
