NWS issues a Red Flag Warning due to dry days expected with winds up 25 MPH.

Guam - A Red Flag Warning is now in effect for Guam until Monday morning. Also labeled as a Fire Weather Watch, this warning means that critical fire weather conditions are forecast to occur.

 

In its statement, the National Weather Service explains, "Very dry weather will continue through Saturday. A shear line to the north may bring a few showers...but not enough to alleviate the dry conditions. As the shear line approaches...RH (relative humidity) will increase slightly while winds will increase as well. The KBDI (Keetch-Byram Drought Index) is already in the extreme range and is only expected to continue to increase." 

 

While the watch is in effect, especially during the most dangerous times of late morning through early evening, residents are discouraged from outdoor burning as fire could spread quickly, and as flying embers and ash may start spot fires downwind.

 

Besides the Red Flag warning, currently several other advisories are also in effect. Airport Wind Advisory was issued earlier today, due to high winds. In its statement, NWS notes that winds today are expected to blow "at 18 to 25 knots with gusts to 30 knots," which is about 20 to 28 MPH with gusts to 34 MPH.  Marine related watchesboth High Surf and Small Craft Advisorieswere extended to be in effect until 6 PM (CHST) this Saturday.
