The National Weather Service in Missoula has issued a lake Wind
Advisory for Flathead Lake... which is in effect from 6 am to 9 PM
MDT Monday.

* Impacts/timing: strong, gusty northeast winds will develop
Monday morning all across northwest Montana from a cold front
sliding southwest out of Alberta Canada. Cooler air settling in
above the Warm Lake, along with the winds, will help create very
choppy conditions on Flathead Lake. Worst conditions are
expected to be on the southern half of the lake from 10am to
4pm.

* Winds: sustained northeast 15 to 25 mph, with gusts approaching
40 mph.

Precautionary/preparedness actions...

A lake Wind Advisory indicates that winds will cause rough chop
on area lakes. Small boats will be especially prone to capsizing.

Note... the experimental wave height forecasts are representative
of the mid lake waters and downwind shores. Wave heights may be
significantly less on upwind shores.
