Fire Weather Watch

... Fire Weather Watch in effect from Saturday morning throughSunday evening for scattered thunderstorms and critically dryfuels for the central Oregon Cascades and foothills and the southern half of the north Oregon Cascades and foothills and the central Oregon Coast Range...

The National Weather Service in Portland has issued a FireWeather Watch... which is in effect from Saturday morning through Sunday evening. An upper level low pressure system will remain off of theCalifornia coast for the next several days. The hot temperatureswe saw this week have dried out fuels to critical levels across thearea.

Increasing moisture with the low will bring the necessaryingredients into place for the development of scatteredthunderstorms across the district. The combination of lightningand critically dry fuels will result in an elevated risk formultiple ignitions. The highest potential for significantlightning producing thunderstorms will be on Saturday and Sundayafternoon and evenings... however... this may be a long lived eventand this watch may need extending in the future.Precautionary/preparedness actions...

A Fire Weather Watch means that critical fire weather conditionsare forecast to occur. Listen for later forecasts and possible flag warnings.
