Knowing what each one means is key

ORLANDO, Fla. – This week marks Hurricane Preparedness Week across the country.

As hurricane season approaches, it’s important to know the different watches and warnings issued by the National Weather Service. Here is a breakdown of the tropical alerts you may come across during hurricane season:

Hurricane Watch

  • Hurricane conditions (sustained winds of 74 mph or greater) are possible.

Extreme Wind Warning

  • The first ever extreme wind warning issued for Brevard County was in 2016 during Hurricane Matthew.
