Heatwave On Tap For Pleasanton This Week

PLEASANTON, CA — Temperatures in Pleasanton and across the Tri-Valley are expected to rise dramatically over the next 24 hours, according to the National Weather Service.

From Thursday to Friday, temperatures could heat up nearly 10 degrees, from 83 to 92 and remain in the 90s through the weekend, according to the latest forecast from the weather service.

Inland cities like Pleasanton will likely see highs into the lower to mid 90s just in time for things to cool down for a "nice summer weekend," weather officials said, adding "Models suggest a decent cool down by Sunday."

Here's what the day-by-day forecast is shaping up to be in Livermore:

According to the Livermore-Pleasanton Fire Department, the current fire danger level was "high" on Thursday afternoon. As temperatures rise Friday and through the week, that dial could move up to "very high" or "extreme."

Fire danger is assessed online by fire personnel in 12-24 hour intervals. The level of Fire Danger is based on a mixture of local wind, temperature and humidity.

"Expected Fire Weather warnings from High to Extreme impose the greatest threat to our community, fire personnel and public," according to the fire department.

During times of "high fire danger," the Livermore-Pleasanton Fire Department offers the following guidance:

• Non-Landscaped open space Parks are permitted open
• Use of open flame devices (BBQ's, Fire Pits) in designated areas only
• No Smoking in Wildland Urban Interface Areas, open space, grass, or other combustible landscape
• Motor Vehicles should stay on paved roads only, Tow chains shall be secured from dragging
• Mechanical fuel fired equipment should be limited to before 10 a.m. and after 6 p.m. in grassy or mountainous lands
• Fireworks are illegal and should NEVER be used

As inland areas are expected to see continued temperatures in the 90s this week, health officials typically urge residents to be extra mindful of exposure to the outdoors, especially for at-risk adults, older adults and children.

While a heat advisory has not come into effect, the NWS will typically recommend the following if temperatures rise into the 90s or 100s:

• Remain in air conditioning.
• Limit strenuous outdoor activities during the hottest hours.
• Not leave kids or pets in cars.
• Stay hydrated.
• Give extra care to the elderly, kids, pets and plants.
• Be wary of hot pavement when walking dogs.
• Be wary of rip currents at the coast.
• Wear light-colored clothing with a hat.

The news comes as dangerous heat spreads in other areas of the nation like the Mid-Atlantic, Ohio Valley and the Southeast through today.
