Extreme heat advisory, watch, warning: What's the difference?
PORTLAND, Ore. (KOIN) – Dangerous heat is coming to Oregon this weekend, and the state’s office of emergency management wants you to be prepared.
The National Weather Service issued an Extreme Heat Watch for much of the Portland metro area from Friday through Sunday evening. Meanwhile, southwest Oregon was issued an Excessive Heat Warning from Friday afternoon through 8 p.m. Monday.
But what’s the difference? Here’s what it means to be under a “warning,” “watch,” or “advisory,” per NWS guidelines.
Warnings, Watches & Advisories
Extreme Heat Warning: Extremely dangerous heat is expected or occurring. Avoid outdoor activities, especially midday. Stay indoors in air-conditioned spaces, drink plenty of water, and check on family and neighbors.
Extreme Heat Watch: Extreme heat is possible in the future. Prepare to suspend outdoor activities and identify nearby cooling shelters or friends/family with AC.
Heat Advisory: Heat will be dangerous but may not reach warning levels. Limit time outdoors, especially during the hottest part of the day, and stay in cool spaces as much as possible.
How to Stay Cool
The City of Beaverton announced Thursday that it plans to open an after-hours cooling center at the Beaverton City Library Main (12375 SW Fifth St.) from 6 p.m. to 9 p.m. on Friday, Saturday and Sunday.
Regular cooling hours will also remain open at Beaverton City Library Main and Murray Scholls Branch (11200 SW Murray Scholls Pl., Suite 102) during normal hours.
As of Thursday afternoon, Multnomah County officials do not plan to open cooling centers to those looking to beat the heat, as current forecasted temperatures have not reached county thresholds to do so.
Without access to a cooling center, there are still several ways to cool off. Residents in Multnomah County are encouraged to find splash pads or libraries near them via the county’s interactive cooling map.
The office of emergency management also recommends the following:
- Drink water regularly and avoid sugary or alcoholic beverages.
- Wear lightweight, breathable clothing.
- Take cool showers or spend time in air-conditioned environments.
- Keep windows closed during the day and open at night if air quality allows.
- Never leave children, adults, or pets in parked vehicles.
- Limit physical activity during peak heat hours.
