Storm surge levels will be highly dependent on the eventual track, size, and intensity of the system. There is a high degree of uncertainty in the forecast at this time and storm surge values are expected to change as forecast confidence increases.
Wind and tornado:
Sustained tropical storm force winds with higher gusts are forecast with the strongest winds expected along the immediate coast.
These winds could result in minor damage mainly to trees, power lines, and weaker structures.
A few tornadoes will be possible in the storm’s rain bands. Tornadoes in these situations are typically short-lived, but they move very quickly.
