Safety Talking Point

Tips For a Healthy Holiday Season

If the holidays sometimes leave you feeling overwhelmed and out of control, you’re not alone! Here are some key things you can do to stay happy and healthy throughout the busy holiday season.

  • Keep up healthy habits. Make a pact with yourself during the holidays. For example: “For the next three weeks I will move more and do something active every day, have a healthy breakfast and limit the sweets, and get at least seven hours of sleep each night.” If you don’t completely give up your healthy habits, you won’t feel like you have to start over once the holidays are in the rear-view.
  • Beware of party perils. Special holiday events often serve up extra helpings of less-than-healthy foods.  If you’re a guest, eat a healthy snack before you go to avoid overdoing it at the event. If you’re the host, challenge yourself to offer some delicious and healthier options using our recipes and cooking tips. Your guests will thank you.

Executive Summary

  • Partly cloudy today with mild conditions
  • Weak Santa Ana winds will bring a slight warming and drying Thursday/Friday
  • A strengthened sea breeze Saturday will usher in higher humidities through the weekend
  • Breezy this weekend, particularly over mountain ridges and desert slopes
  • Additional Santa Ana winds next week with minimal impacts
  • The FPI will be Normal in all districts through the foreseeable future

Forecast Discussion

Partly cloudy skies today will be followed by weak Santa Ana winds tomorrow and Friday. Winds aren't expected to be impactful but will bring sunnier skies and slightly warmer, drier conditions. Onshore flow this weekend will usher in some moisture from over the ocean, dropping our temperatures a bit and bringing a slight chance for some light rain Saturday night into Sunday, though it’s more likely to be a little drippy fog. It will also be fairly breezy throughout the service territory, though nothing we'd expect to see impacts from. Gusts over mountain ridges and desert slopes may reach as high as 50-55 mph, while the rest of the service territory could see gusts of 20-25 mph even at the coast. Early next week, another round of Santa Ana winds will bring additional warming and drying to the service territory. Models are showing this event to be weak to locally moderate in strength, but recent rainfall and the beginnings of a new grass crop will keep fire potential pretty low.

The next potential storm we're tracking looks to be around the 18th-20th. Models continue to waiver run by run, and the European model isn't convinced there's even going to be a storm. We'll continue to monitor and provide updates as forecast confidence increases.

Fire Discussion

Recent rainfall and periods of sunshine have initiated a new grass crop, helping reduce overall fire potential. Though we will continue to have periods of Santa Ana winds, greener grass and higher fuel moistures will keep the FPI in Normal for the foreseeable future.
