ROSEBURG, Ore. — The first significant warm up of the summer is expected to arrive this weekend, bringing elevated heat risk to much of southern Oregon and northern California from Sunday through Tuesday.

The National Weather Service office in Medford says the hottest temperatures are expected Monday, with a cooling trend forecast for the latter half of next week.

For valleys west of the Cascades, including Roseburg, Medford and Grants Pass, temperatures are expected to climb into the upper 90s and low 100s. East Side communities are expected to see highs mainly in the upper 80s and 90s.

Roseburg is forecast to reach 98 degrees Sunday and Monday, followed by 94 degrees Tuesday. Grants Pass and Medford are both forecast to reach 103 degrees Sunday and Monday, with triple-digit heat continuing in Medford on Tuesday.

The heat risk is expected to be moderate to major for heat-related illnesses. That level of heat can affect anyone without effective cooling, adequate hydration or regular breaks from the sun.

Because these are expected to be the warmest temperatures of the year so far, many people may not be used to the heat yet. Officials are encouraging people to take precautions, especially during the hottest part of the day.

Recommended safety steps include:

  • Drink water before feeling thirsty.
  • Wear lightweight, light-colored clothing.
  • Take frequent breaks in air conditioning or shade.
  • Shift outdoor activities away from 10 a.m. to 4 p.m.
  • Check on older adults, young children, pets and others who may be more vulnerable to heat.
  • Never leave children or pets inside parked vehicles.

Area waterways may also look inviting during the heat, but officials are reminding people that rivers and lakes are still cold. Cold water can quickly affect swimming ability and increase the risk of shock or drowning.

Temperatures are expected to ease later next week, with Roseburg forecast to drop back into the 80s by Wednesday and Thursday.
