Things get interesting this weekend as a low pressure system sets up just off the coast of southern California. Light southeasterly flow will bring weak to moderate instability along with moisture to western Nevada and the eastern Sierra. These two ingredients will create widespread thunderstorm activity for this weekend through early next week, with Saturday looking the most promising for stronger storms. Flash flooding will be the main issue with these storms, especially since they will be slow movers. Make sure to make the necessary flash flood preparations so you can be ready just in case. For example, clean out your gutters and any drainage paths, clear away debris from nearby storm drains, park your vehicles away from flood prone areas, and avoid camping along streams and rivers. If you do encounter any flooded roadways, remember to turn around and don’t drown!
