It’s killed hundreds in Haiti and could deliver major damage from Florida to the Carolinas.
Now as the storm creeps up the coast of Florida, and Georgia and South Carolina after, forecasters are ringing every bell within reach about its dangers. Matthew is “unlike any hurricane in the modern era,” says the National Weather Service in Jacksonville, Florida. “A major hurricane [has] not impacted this area in 118 years, since October 2nd 1898.”
According to these doom nuggets from the worst-case scenario described in Jacksonville’s media briefing, it could deliver gusts up to 140 mph, a storm surge “MUCH larger” than 2012’s Sandy in New Jersey, and… well, just read:
• Major Hurricane Matthew is forecasted by the National Hurricane Center to move DANGEROUSLY CLOSE [to] the Florida First Coast and Southeast Georgia Coast Friday through Friday night into Saturday with catastrophic impacts expected along and near the coast….
• The western eyewall is forecasted to move along a portions of the coast with sustained winds 115 to 125 mph and gusts to 140 mph expected in the Flagler and St Johns County Coastal areas.
• Winds could be higher in high rise structures such as in Downtown Jacksonville possibly strong Category 4 intensity!
• Some of the lowest barrier islands will be completely overtopped with large battering waves and life threatening flooding. Barrier islands are likely to breached and it is extremely possible that new inlets will be cut in the worst affected areas.
• Please, Please heed the advice of public and emergency management officials. 40 people in New York and New Jersey did not heed these warning during Sandy and died in the storm surge!
The surge is expected to top 9 feet above ground level—6 to 9 feet in St. John’s River and other rivers—and breakers could crash down from heights of 20 to 25 feet, delivering “total devastation” to barrier islands. All in all it sounds deadly serious, and anybody who choses to ignore evacuation orders—looking at you, guy— is in for a rough ride.
