Get Ahead of the Storm - 5 Severe Weather Hacks

There’s really no place that’s 100 percent safe in Florida when it comes to hurricanes.

Even Orlando got hit twice in 2004 by hurricanes Charley and Frances.

And, although Florida enjoyed a more than 10-year hurricane drought after 2005’s Hurricane Wilma, Hurricane Hermine made landfall in the Florida Panhandle in 2016. 

Still, has ranked Florida’s cities based on their evaluation of NOAA-identified storms from 1965 to October 2014, doling out scores based on the number of storm events, number of storm-related deaths, property damage and storm-related injuries.

The top 10 safest cities in Florida during a hurricane, according to the insurance study, are:

  1. Leesburg
  2. Orlando
  3. Sanford
  4. Kissimmee

Heat Index: What is it? Why does it matter?

Published: Thursday, May 24, 2018 @ 6:35 AM

Meteorologist Kirstie Zontini looks into what the heat index is and why it is important.

 In the winter we talk about wind chill and in the spring and summer, it is the heat index that is important, according to Storm Center 7 Meteorologist Kirstie Zontini.

RELATED: What is UV Index and how to protect your skin

Both are apparent or "feels like" temperatures. The heat index is a "feels like" temperature that looks at the actual air temperature and how much moisture is in the air, either with relative humidity or dew point. When it is hot, it can be uncomfortable. When it is hot and muggy, it is a different level for our bodies. 

The amount of moisture in the air impacts how well our bodies can cool off. When you are hot, your body starts to sweat, that sweat is then evaporated from your body into the atmosphere. If the moisture content of the air is high, it is harder for that evaporation to take place, and harder then for your body to cool down. 

LISTEN: Cloudy with a chance of Podcast: A podcast for weather fans 

Here is the actual equation for calculating heat index: 


HI = -42.379 + 2.04901523*T + 10.14333127*RH - .22475541*T*RH - .00683783*T*T - .05481717*RH*RH + .00122874*T*T*RH + .00085282*T*RH*RH - .00000199*T*T*RH*RH


As the air temperature and relative humidity increase, the heat index will as well. If it is 88 degrees with a relative humidity of 55%, the heat index would be 93 degrees. If it was 100 degrees with a relative humidity of 55%, the heat index would reach 124 degrees. This makes being outside when it is hot and humid more dangerous. 

  • 80-90° - Use caution. Prolonged activity outside or exposure could be dangerous. 
  • 90-103°- Use extreme caution. Lengthy exposure can cause heat cramps, heat stroke or heat exhaustion
  • 103-124°- Danger! Heat cramps and heat exhaustion likely. Prolonged exposure can lead to heat stroke.
