As of 8 p.m. EDT on Wednesday night, Matthew was swirling through the Bahamas with maximum sustained winds of 115 miles per hour, making it a Category 3 storm. "Matthew is likely to produce devastating impacts from storm surge, extreme winds, and heavy rains in the Bahamas," the National Hurricane Center stated in its forecast discussion this evening. As it takes dead aim on Florida, Matthew is forecast to strengthen over unusually warm waters. The storm is expected to move very close to the east coast of Florida by Thursday morning, and then cruise north, hugging the shoreline. Hurricane conditions are forecast for much of the coast, beginning late Thursday and then spreading northward on Friday.
Bizarrely, the forecast is for Matthew to take an extreme turn to the east, and then start heading back south, as the forecast track above shows. Computer models suggest that the storm could even loop back toward Florida early next week. If this is indeed what happens — and by no means are forecasters sure about this — the storm would likely approach Florida in a weakened state. But even if so, Matthew's return could bring more torrential rain and storm surges to coastal areas already devastated from the first encounter with this ferocious storm. For now, keep in mind that this is just a possibility — albeit a scary one.
This prototype Storm Surge Watch/Warning Graphic from the National Hurricane Center shows locations most at risk for life-threatening inundation from storm surge. Keep in mind that it is a prototype, and that "due to forecast uncertainty, the actual areas that experience life-threatening inundation may differ from the areas shown on this map," according to the NHC.

"There is a danger of life-threatening inundation during the next 36 hours along the Florida east coast from Deerfield Beach to the Flagler/Volusia county line," according to the National Hurricane Center. Out to 48 hours, life-threatening inundation is possible as far north as the Savannah River in Georgia. The graphic above is a screenshot I took of a prototype storm surge warning graphic from the hurricane center. Check out that long stretch of coastline in purple. Here's where the risk for life-threatening inundation is most severe. Now, let's zero in a bit:

In 2004, Hurricane Jeanne is reported to have caused $100 million of damage to the space center, Cape Canaveral Air Force Station, and Patrick Air Force Base — even though its winds were of minimal hurricane strength. Should Matthew strike with stronger winds and also push up inundating storm surges... Well, let's fervently hope not.
