Why A Heat Advisory Might Not Be Issued, Even If The Temperature's Broken All Records

Miami hasn't had just one hot day this year, but rather weeks and weeks of intense heat.

On Tuesday, the temperature at Miami International Airport reached 98 degrees Fahrenheit, but no heat advisories or excessive heat warnings were issued.
