Fifteen inches. That is the upper-end rainfall forecast for parts of Mexico’s Pacific coast as Hurricane Trudy bears down as a major hurricane this weekend — a volume of water that turns hillsides into mudslides and streets into rivers, and a figure that has emergency managers across three states on high alert.
Trudy packed winds of up to 140km/h on Friday and is expected to bring hurricane conditions to the coast of Jalisco and Colima by Saturday night, with the storm’s centre forecast to pass very near the shoreline. The National Hurricane Center warned of 4 to 8 inches of rain broadly, with isolated totals up to 15 inches across Michoacan, Colima and Jalisco, according to Reuters’ reporting.
Why rainfall is the real killer
In hurricanes, wind makes the headlines but water does the killing — historically, most hurricane deaths come from flooding and storm surge, not wind. Emergency managers repeat the point every season because the public consistently underestimates it: a Category 3 wind field with 15 inches of rain is far deadlier than its wind speed alone suggests.
Fifteen inches on steep coastal terrain means flash floods, landslides and washed-out roads; in Acapulco, ports closed to small craft and fishermen hauled boats ashore well before the worst arrived.
Disaster response on this scale strains even well-drilled systems — a lesson in the human cost of long emergencies — and governments under pressure have little margin for error when the rain starts falling.
What decides it
Track and speed: a slow-moving storm dumps more rain; a direct hit maximises surge and wind damage. Forecasters expect to refine Trudy’s track through Saturday, and Mexico’s civil protection agency has urged residents to heed evacuation orders early rather than waiting to see.
The weekend will be measured in inches — and, everyone hopes, not in lives lost. For a coastline still recovering from recent storms, Trudy is arriving at the worst possible moment; preparation, this time, is absolutely everything.
