The criteria determining when the county opens a cooling center includes meeting the following conditions:

  • The National Weather Service issuing a Heat Risk Level 3 warning or greater for at least three consecutive days; AND
  • The National Weather Service issuing an Excessive Heat Warning; and/or
  • A forecast of high daytime temperatures accompanied with overnight low temperature of at least 75 degrees or higher; and/or
