A record-breaking heatwave is about to hit the west coast of the United States during the worst drought on record.
From California to Oregon and Washington State, temperatures are expected to remain well above normal for days. The National Weather Service has issued warnings.
⚠️Record-Breaking and Dangerous Heatwave coming to the West. Over 80 sites are forecast to break daily high temperature records starting this weekend. All-time June monthly records could also be broken in some locations in the Pacific Northwest.

What is that going to do to the 2021 grape harvest and all other crops? The last time California had a record-breaking heatwave, it came at harvest time in September 2017 and turned the grapes into raisins.
Update 28-06-21
It's hit as predicted and it is unprecedented. Portland, Oregon reached a temperature of 112 degrees Fahrenheit (44.4 Celsius) on Sunday, breaking the all-time record of 108 F (42.2C) which was set just a day earlier. Seattle this 104.
When temperatures reach this high, grapes shut down to conserve water. If this continues, mitigation strategies will have to be implemented.
