Key Messages

  • Not as cold tonight with clear skies and light to calm winds. Dry for most through Monday Night.
  • Increasing chances for rainfall across coastal areas for this upcoming work week as a offshore Storm gradually approaches from the south. The system likely brings significant marine impacts in the form of strong winds, rough seas, and beach erosion through much of the upcoming week.
