Updated Sept. 8 at 1:10 p.m. to include more detailed storm surge forecast. Dozens of people died or were injured when Hurricane Henri slammed into Haiti, Jamaica and Cuba with devastating winds and torrential rain this week. The storm caused widespread flooding, looting and other damage. Though weather systems are swirling in North America, this region gets hit hardest by tropical systems every couple of years. In
2016, tropical storm Hermine took down power lines and left many in Washington without power. Storm Angus killed more than 30 people in Bermuda last year. In 2013, Hurricane Sandy pounded the Eastern Seaboard with destructive winds and heavy rain. Before landfall, Henri was a Category 1 hurricane with winds of 75 mph. By the time it hit Cuba, however, the storm ramped up to Category 5 with sustained winds of 150 mph,
before it weakened to Category 3 with 75 mph winds after landfall. It raked through a stretch of the Caribbean, downing trees and power lines, damaging homes and killing 15 people in Haiti. The National Weather Service has been working on updating its climate models to try to better anticipate and model tropical systems. The updated model projections feature many more runs than previous models, according to research
published by research scientist Christopher Hofstra of the U.S. Geological Survey’s Tropical Rainfall and Climate Modeling Facility in Costa Rica. One result is the inclusion of data from tropical cyclone intensity-and-track models as well as reconnaissance aircraft to better illustrate where storms will grow and strengthen.
