Hurricane season is here, and we want to help you stay ready. This guide will update you on evacuation zones, refresh you on preparing for a storm, and provide some resources to stay weather-aware.

The Atlantic hurricane season started Sunday, June 1, and runs until Sunday, Nov. 30. Forecasters predict this season will be busy.

Predictions

The National Oceanic and Atmospheric Administration’s outlook predicts a 30% chance of a near-normal season, a 60% chance of an above-normal season, and a 10% chance of a below-normal season. Here’s the forecast:

  • 13 to 19 total named storms (winds of 39+ mph)
  • 6 to 10 of those are expected to become hurricanes (winds of 74+ mph)
  • 3 to 5 are predicted to become major hurricanes (category 3, 4, or 5; with winds of 111+ mph)

Evacuation zones

State leaders unveiled new hurricane evacuation zones last year to better accommodate the growing population and to avoid potential hazards. Factors like storm surge risk + flood susceptibility played a role in creating the new zones.
