The Heat Wave In The Pacific Northwest Is Buckling Roads And Melting Power Lines.


This week's scorching heat is scorching the Pacific Northwest, shattering temperature records and causing damage to infrastructure in a region known for its mild climate.

Portland, the state's most populous city, broke its heat record of 108 degrees on Sunday when the temperature reached 112, and it may reach 115 on Monday. Salem, the state's capital, broke its heat record two days in a row, with the temperature reaching 113 degrees on Sunday and 114 degrees on Monday.

Temperatures in Washington were slightly lower, due in part to a marine layer moving in off the coast, but Seattle had three consecutive days of triple-digit weather for the first time on record on Monday.

The heat wave has caused some unusual issues in the region, where temperatures are typically low enough all year that many people do not have air conditioning in their homes.

The Portland Streetcar, which serves downtown Portland, halted service on Sunday and plans to remain closed until at least Tuesday morning, citing a melted power cable.

The city's MAX Light Rail Service also shut down, citing high temperatures as a cause of strain on the power grid and the overhead wires that power its trains.

Communities affected by the heat wave are also dealing with buckling roadways, which make them unsafe to travel on, as well as the risk of sinkholes caused by thermal expansion, which occurs when concrete or asphalt becomes too hot and begins to expand, with nowhere to go but up.

A section of pavement has come loose on NB I-405 at I-5 in Tukwila, closing the SB I-405 ramp to northbound I-5, but leaving the HOV ramp open. WSP has it coned off, and our maintenance crew is on its way to make repairs. pic.twitter.com/p05K2XzN5P — WSDOT Traffic (@wsdot_traffic) June 27, 2021

The effects on transportation can make it more difficult for people to seek relief from the heat at cooling centers or at the homes of friends or relatives who have air conditioning. While approximately 91% of homes in the United States have air conditioning, only 78% of homes in Portland and 44% of homes in Seattle have it.
