The coast of South Central Oregon was the target of the warning.
“The current Freeze Warning will be allowed to expire as daytime warming continues,” the National Weather Service says.
“Those who have respiratory disorders may experience complications as a result of poor air quality. Unprotected skin exposed to these low temperatures may suffer from frostbite and hypothermia. According to the weather service, “freeze conditions could damage unprotected outdoor plumbing and kill crops and other sensitive vegetation.”
Freeze watch or warning – this is what it means
Freeze warnings are in effect from May through October (though they may be extended if needed), during which time low temperatures of 29 to 32 degrees are predicted. A freeze watch might be issued a few days in advance if temperatures have the potential to drop below these criteria.
The weather service says there isn’t much you can do to preserve plants if your location is under a freeze warning or watch. Depending on the severity of the weather, the freeze may probably kill your sensitive plants, so if you can relocate them inside, do so.
United Robots offers a service called Advance Local Weather Alerts that gathers the most recent information from the National Weather Service using machine learning.
