Cold Water Safety

Temperatures will remain hot early this week. There will be a moderate risk for heat related illnesses during this time for areas away from the immediate coast. This means this level of heat affects most individuals sensitive to heat, but especially those without effective cooling and/or adequate hydration. Temperatures will trend back toward normal from Tuesday onward.

Scattered thunderstorms are expected in southwest Oregon and northern California Monday afternoon and evening. There is a marginal (10-15% chance) risk for severe thunderstorms with a 5 % chance of strong damaging winds (60 mph or more) and/or large damaging hail (1” or more) across portions of Josephine, Jackson, Klamath, Lake, Siskiyou and Modoc counties. Lightning will be a risk near all storms. Remember, if thunder roars, go indoors. If you have outdoor plans on Tuesday, stay weather aware and have multiple ways to receive warnings.

Isolated to scattered thunderstorms are expected to continue through mid-week, with the focus of activity shifting eastward each day. The main threats will be lightning hail and strong gusty outflow winds. Remember that lightning is deadly - when you hear thunder, seek substantial, covered shelter and remain there until 30 minutes following the last rumble of thunder.

While air temperatures will be hot Sunday and Monday, area rivers and lakes remain cold and swift. Always wear a life jacket when you’re recreating or swimming near water.
