Summer Heat Waves

Summer is well on its way and heat waves can be expected.

Excessive heat has caused more deaths than other weather-related deaths – including floods.

A heat wave is a prolonged period of excessive heat, often combined with excessive humidity. Generally temperatures are 10 degrees or more above the average high temperature for the region during summer months, lasting for a long period of time and ocurring with high humidity as well.

Know the Difference

Excessive Heat Watch – Conditions are favorable for an excessive heat event to meet or exceed local Excessive Heat Warning criteria in the next 24 to 72 hours.

Excessive Heat Warning – Heat index values are forecast to meet or exceed locally defined warning criteria for at least two days (daytime highs = 105 to 110 degrees Fahrenheit).

Heat Advisory– Heat index values are forecast to meet locally defined advisory criteria for one to two days (daytime highs = 100 to 105 degrees Fahrenheit).
