PHOENIX — Extreme heat returns this week!

A strong ridge of high pressure will build over Arizona, driving afternoon highs well above normal and into near-record territory.

An Extreme Heat Warning is in effect Tuesday and Wednesday for the Grand Canyon below 4,000 feet. An Extreme Heat Watch is also in place for central, southern, and western Arizona Wednesday through Friday.

That means Wednesday, Thursday, and Friday will be ABC15 Weather Action Days, as this dangerous heat can be life-threatening.

Be sure to plan ahead! Stay hydrated with water and electrolytes, limit outdoor activities between 10 a.m. and 6 p.m., bring pets inside, and remember that many hiking trails will be closed.

Widespread moderate to major heat risks are expected this week, putting most people at risk for heat-related illnesses. Know the signs of heat exhaustion and heat stroke.

Monsoon storms will mainly impact northern and eastern Arizona early in the week, with the Valley’s best storm chances arriving later, especially Friday through Sunday.

Stay with ABC15 for the latest updates as the week unfolds.
