Hell is coming! Hot and dry forecast with wildfires in April, May 2021 for Southwest, USA

Wildfire season 2020 in California and other states in Southwest, West and Rocky Mountains was devastating and the worst in all-time US history. Only until the end of October 2021, 13 millions acres was destroyed in the USA /https://gacc.nifc.gov/sacc/predictive/intelligence/NationalLargeIncidentYTDReport.pdf/ and wildfires from the south was spreading into western Canada quickly, too.

Los Angeles, San Francisco, Seattle or Vancouver in the smoke from wildfires or directly, with a wildfires, that was a sad reality of last year along West Coast, USA.

In the winter and early spring, wildfire activity was reduced and during late March, California still reported very cold weather, even with all-time temperature records /https://mkweather.com/livemore-california-the-coldest-temperature-in-110-years-11c-30f-extreme//.

Gradually, however, tropical air in Mexico started to warming up and eastern parts of the USA hit the first warm spells /https://mkweather.com/hot-air-from-mexico-467c-has-shifted-above-florida-35c-virginia-30c-and-new-york-28c//.

Gradually, the first heatwaves, not only in Southwest, but across all continent, are during the next period expected /https://mkweather.com/extreme-heatwave-will-shift-from-mexico-to-greenland-the-first-hot-times-in-the-usa-and-canada-between-3-12-april//.

Wildfires from Mexico then, should quickly spread into Southwest, again /https://mkweather.com/wildfires-threaten-mexico-city-monterrey-mexico//.

Not only upcoming heatwave, but after a short break in the middle of April, all period between 20.- April and 20. May should be according to ECMWF long-term outlook in Southwest extremely warm, dry and with spreading of wildfires.

It appears, that Wildfire season 2021 in California, Southwest, West and Rocky Mountains this year will start earlier than usually, what should have devastating impact to development of situation during summer months.

Summer driven by La nina is still forecasted to be extremely warm and dry in southern parts of the USA /Mkweather forecasts for Summer 2021 for every continent will be updated already in next days/, therefore, upcoming Wildfire season 2021 should surprise with unusual power and maybe compete with the previous, record season.
