While the monsoon officially began June 15 — a day after three consecutive days of dew points greater than 55 degrees — Tucsonans have been teased by recent cloud-cover and high humidity.

Tucson received no rainfall from June 15-30, according to the National Weather Service, and only trace amounts through July 10. That’s not uncommon; the average rainfall in the second half of June is 0.24 inches while July averages 2.07 inches.

It’s unpredictable when heavy storms will surface, but it’s important that people are prepared for when storms do strike.

Lightning, strong winds, dust storms, flash floods and tornados are all cause for concern.

Here are some safety tips from the National Weather Service.
