A Heat Advisory is in effect from 11:00 a.m. to 11:00 p.m. Wednesday for mountain areas in southern Oregon with a Fire Weather Watch in place for some areas as well.

Forecasters at the National Weather Service said high temperatures of 90 to 95 degrees are expected with isolated areas reaching up to 100 degrees. The Advisory area includes the south-central and southern Oregon Cascades and Siskiyou Mountains, including Crater Lake and Diamond Lake.

Forecasters said instability increases Wednesday with scattered thunderstorms possible. Thunderstorms are expected to start dry and progressively become wetter. In addition to the threat of new fire starts, a dry and unstable layer will support gusty and erratic outflow winds with any thunderstorms. Plume-dominated fire activity will be possible with new or existing fires due to the hot, dry and unstable conditions.

A Fire Weather Watch means that critical fire weather conditions are possible during the watch time. These could promote the rapid spread of wildfires which could become life-threatening.
