The official Atlantic hurricane season is from June 1 to November 30. The majority of tropical activity occurs during these six months. Always be prepared for a storm year-round.

Storm Surge Evacuation Planning Zone

Storm Surge & Flooding

A storm surge has the ability to cause extensive damage posing the greatest threat during a severe weather event, and it is the main reason evacuation orders for an area are issued. The Miami-Dade Office of Emergency Management (OEM) has identified Storm Surge Planning Zones within the county. To determine if your location is within a storm surge planning zone, visit the Storm Surge Planning Zone page or call Miami-Dade County Answer Center at 3-1-1.

Upon identification of a threat, the OEM or County Mayor will use local media to relay pertinent information, such as evacuations and shelter openings. It is important to monitor the news for this information. Remember that these planning zones deal strictly with storm surge and you will need to determine if your home is safe to remain in during a hurricane.

Wind & High-Rise Buildings

High winds can cause considerable damage from the pressure they put on windows and buildings, as well as damage caused by unsecured items and debris which become projectiles capable of causing death, great bodily injury, or serious damage to property. Winds are stronger as you go higher, which should be of concern to the many hi-rise condominium dwellers living in the City.
