Storm Chances Rise Sunday Through Tuesday
Sunday brings a 50% chance of showers and thunderstorms, with temperatures near 89 before daytime showers and storms become possible. Locally heavy downpours are possible Sunday through Tuesday, when scattered to numerous showers and storms remain possible.
Showers and storms remain possible Wednesday into Thursday, when the forecast period ends. Highs are forecast in the upper 80s to around 90 through Wednesday.
Beachgoers Face Choppy Conditions
Onshore winds and elevated surf are expected to support elevated or dangerous rip-current conditions at area beaches. Swimmers should use lifeguarded areas, avoid entering the water alone and check local beach conditions before heading out.
