Weather Alert: Heat Advisory Today - take proper precautions |Read More >>

In Hillsborough County, it’s important to know your severe weather risks year-round, but especially from June-November.

The Atlantic Hurricane season lasts from June 1-Nov. 30. During that time is when we see the most amount of tropical weather activity. 

There are several different types of systems to be aware of, each bringing their own levels of intensity and risks. 

National Weather Service Tropical Definitions

Understanding forecast cones 

Once a tropical system is identified, the National Hurricane Center will release a forecast cone that represents the probable track and impacts of a tropical cyclone in the days days and hours leading up to the storm’s projected landfall. 

Even if your home is outside the cone, you could still feel storm impacts and should be prepared and stay safe.  

Be sure to monitor local TV stations, radio stations, and official Hillsborough County social media for updates.  

Storm impacts 

Depending on the severity of the storm, impacts can include flooding and/or wind damage to homes and properties. 

Significant rainfall or storm surge can flood coastal and low-lying areas.

 

Storm surge, the danger of rising water moving inland from the shore, is extremely dangerous and can be deadly. It’s crucial to know your evacuation zone, and heed evacuation orders and warnings from emergency officials. Evacuation zones are based on storm surge dangers and the probability of storm surge in that area. 

Flood Information and Safety

Heavy winds and tornadoes from tropical systems are life-threatening and can cause significant damage to your property. Be sure to secure valuables before the storm arrives, and head to an interior room with no windows until the storm passes.  

The storm has passed, what’s next? 

Just because a system has passed and the sun is shining, does not mean you’re in the clear. 

Stay inside your home, hotel, or shelter until evacuation orders have been lifted. 

Post-storm risks include: 

  • Downed power lines 
  • Damaged trees and other debris 
  • Dangerous flooding 

 If you must go out after a storm, be aware of your surroundings and do not attempt to drive in floodwaters. 

The National Weather Service (NWS) says more deaths occur due to flooding than from any other storm-related hazard, including lightning and powerful winds.
