Record Heat Dome Sweeps Across Nearly Entire US on Historic Day of Records
A massive record-breaking heat wave is currently engulfing nearly all but one state in America with temperatures soaring to unprecedented levels. The extreme weather event has shattered March records across 14 states, including Nevada which recorded its hottest day ever for the month so far this year (March). Officials warn that "basically the entire U.S." will face these scorching conditions as a gigantic heat dome continues to grow in intensity and coverage area over land.
Key Points
-
1A record-smashing heat dome has spread across much of North America after shattering March temperature records in all but one state.
-
2Meteorologists describe the event as 'really bizarre' and predict it may become one of the most expansive heat waves ever recorded, potentially lasting until mid-next week.
-
3Experts attribute an 800-fold increase in likelihood for such extreme events to human-caused climate change while noting current humidity levels are lower than summer conditions.
Developments
Meteorologists describe a record-breaking March "heat dome" as spreading across the US from west to east due to high pressure trapping hot air over large areas of 48 states. While experts note that its physical area may exceed historic events like those in 2012 and 2021, they caution it is likely less intense than summer heat waves because these March temperatures are occurring earlier before the peak danger months arrive.
A record-breaking "heat dome" is moving eastward across nearly half of U.S., threatening to set new March temperature records in at least one-third of the 48 continental states for up a week. Experts warn this extreme event, which has already shattered historical highs since last month and dwarfs previous single-event heat waves like those from 2012 or 2021, is made roughly eight times more likely due to climate change.
A massive eastward-moving "heat dome" has set record highs across 14 states and threatens to become one of American history's most expansive heat waves by trapping hot air over a vast region until mid-April. Meteorologists note that while the physical area may rival historic events like those in 2012 or 2021, it is likely less intense than summer Dust Bowl conditions due to lower humidity and shorter duration as part of March rather than June-July heatwaves.
A record-breaking heat dome is spreading across nearly all U.S., shattering March temperature records in 14 states and potentially becoming one of American history's most expansive events by rivaling those from 2012, a report says. Meteorologists attribute the extreme conditions to human-caused climate change while noting that high pressure acts like a pot lid trapping hot air over regions such as Flagstaff and central Plains for days at a time.
