Beach Hazards Statement

Mid/upper atmospheric moisture will increase late this weekend and the pattern is favorable for thunderstorms with little to no precipitation. Lightning strikes and gusty winds on dry vegetation may increase the potential for fire starts and spread. We continue to assess the amount and location of instability and this is the most uncertain aspect of the forecast. Check back for updates, especially if you have outdoor plans later this weekend into early next week.
