Some Tips to Prepare for Flooding:

  • Move vehicles to higher ground, especially in flood-prone areas.
  • Move items stored in low-lying areas, such as basements or other areas that have flooded in the past.
  • Driving through flooded roads is dangerous!

Living near the ocean we get to enjoy the many things that it has to offer, but we also have to deal with the issues it can bring. One of these issues are the occasionally higher than normal tides, sometimes referred to as “King” Tides. However, as opposed to other natural issues, we know when these high tides will occur far in advance. Check out these expected high tides in the coming month that may impact traffic and parking in flood-prone areas, especially during winter weather. Take note so you don’t end up getting wet by surprise.
