These straight-ahead storms most commonly form in the late spring and summer, when high pressure weather systems—whirling masses of descending air—move north from the tropics into the U.S. Some derechos, however, occur during cooler weather and are most likely to form in the region stretching from Texas across the …
How long can a derecho last?

What do you need to know about Derechos?
Derechos rarely occur without warning, although warning lead times may be comparatively limited during the early stages of storm development. Because protracted and extensive electrical and communication disruptions may occur, set aside emergency water and food supplies, can openers, batteries, and flash lights.
When do derechos occur in the NWS?
The type of derecho that occurs is a good indicator of the weather pattern and also is partly dependent on the time of the year. The occurrence of derechos is divided into two seasons; the “warm” season which is May, June, July and August. 70% of all derechos occur during these four months. The remaining eight month comprise the “cool” season.
