Wider weather episode

Major Hurricane Matthew moved northwest from the eastern tip to Cuba, reaching the extreme western coast of Grand Bahama Island during the evening of October 6 at Category 4 strength. The hurricane continued northwest and was centered approximately 55 miles east of Stuart at 2300LST. Matthew then paralleled the Florida coast, remaining just offshore as a Category 3 hurricane. The eye reached its closest point of approach to land, only 25 miles east of Cape Canaveral near 0800LST on October 7, and was 35 miles east of Daytona Beach around 1100LST, as it continued moving northwest, just offshore the northeast Florida coast. Hurricane force winds (sustained or frequent gusts) affected coastal areas from Vero Beach northward, extending inland across the mainland portions of Brevard and Volusia Counties, with tropical storm force winds experienced across much of the remainder of east-central Florida. The strongest winds occurred along the coast from Cape Canaveral in Brevard County to north or Ormond-By-The-Sea in Volusia County, where Category 1-2 winds were likely experienced. Two direct hurricane-related fatalities and one direct injury occurred, in addition to nine indirect deaths. Preliminary damage estimates across east-central Florida exceeded $580 million, with $514 million reported in Volusia County alone.

A storm surge of 3-6 feet affected the beaches from near the Indian River/St. Lucie County line northward to the Volusia/Flagler County line, along with moderate to major beach erosion, with the highest surge (5-6 feet) and most significant erosion occurring north of Daytona Beach. Farther south, a surge of 2-3 feet occurred, along with minor to moderate beach erosion.

Rainfall totals reached 7-9 inches across parts of Seminole and Volusia Counties, where widespread flooding of streets and low-lying areas occurred. Elsewhere, rainfall totals were generally 2-6 inches, with isolated, minor flooding of poor drainage areas and standing water on roadways.
