It has been a brisk start to the Pacific Hurricane Season. Within the first two weeks of June, there have already been two hurricanes off the Pacific Coast of Mexico recording Cat 4 maximum sustained winds on the Saffir-Simpson Scale. On June 7, Hurricane Aletta, tracking far off the coast of southern Mexico, saw a period of rapid intensification with winds doubling to 140 miles per hour (220 km/h) within 24 hours before weakening and dissipating. The second named hurricane, Hurricane Bud had a similar intensification, going from 50 miles per hour (80 km/h) on June 10, to 132 miles per hour (212 km/h) some 24 hours later. Bud’s legacy now looks to be a weekend of heavy rain over the Baja California peninsula. For the North Atlantic Hurricane Season, the hurricane tally stays at zero.
So, lots of activity already in the Pacific, but overall, how different is storm activity on the Pacific compared to Mexico’s Atlantic Coast? RMS estimates that for Mexico, around 40 percent of the annual average loss from wind comes from the Pacific. To evaluate the complete hurricane risk for Mexico, the upcoming Version 18 release of the RMS® North Atlantic Hurricane Model will model both the Atlantic and Pacific coasts.
