Details

Severe thunderstorms are expected to affect the Boundary Waters
Canoe Area Wilderness early this afternoon for the westernmost
portions of the Boundary Waters, then again late this evening for
all of the Boundary Waters. The storms may produce damaging
winds, large hail, frequent cloud-to-ground lightning, and
locally heavy rainfall. The first round of severe thunderstorms
could happen as early as noon and ending before 5 PM. The second
round of severe storms are expected to arrive late this evening
with the most likely time for thunderstorms between 9 PM and 3 AM
Tuesday.

Now is the time to prepare in case thunderstorms threaten.
Campers should take extra precautions now in order to secure
campsites and make a plan in case of severe weather. For strong
winds, try to keep your tent away from large or decayed trees.
For large hail, use your well-tied down canoe or tent for
shelter. For lightning, sit on your personal floatation devices
or sleeping pads and avoid putting your tent on top of exposed
tree roots to minimize your risk. Monitor NOAA Weather Radio for
updates and possible warnings.
