Southern Nevadans are facing a potentially dangerous and early heat wave this week, with temperatures expected to soar to levels not typically seen until May. Las Vegas could reach 100 degrees in the coming days – a milestone that has never occurred in March or April, with May 1, 1947, holding the record for the earliest triple-digit temperature.
Who is Most at Risk?
The National Weather Service has issued extreme heat warnings through the weekend, cautioning that the unusually high temperatures will be particularly challenging for tourists and regional locals alike. Dr. Joanne Leovy, a Las Vegas family physician and chair of Nevada Clinicians for Climate Action, expressed concern about public health, noting the shock to the system these temperatures will cause.
Parents of young children and the elderly are considered especially vulnerable, as neither group sweats as effectively as adults, hindering their ability to regulate body temperature. Children’s higher metabolisms as well contribute to increased internal heat production. Other high-risk groups include recreational drug users, individuals with pre-existing conditions like diabetes or high blood pressure and those experiencing homelessness.
Dr. Cassius Lockett of the Southern Nevada Health District recommends drinking plenty of water, limiting outdoor activity during peak heat, seeking air-conditioned spaces, and checking on vulnerable individuals.
The heat wave coincides with spring break, potentially increasing outdoor recreation and exposure. Researchers have identified areas within Clark County, including downtown Las Vegas, North Las Vegas, the Historic Westside, and East Las Vegas, that experience temperatures up to 11 degrees hotter due to the urban heat island effect – a result of limited trees and green spaces.
Clark County’s standard response to extreme heat involves activating cooling stations in locations like libraries and community centers. However, research from the Desert Research Institute’s Nevada Heat Lab indicates that awareness of these stations is low, and transportation barriers often prevent those most in need from accessing them. David Almanza, a postdoctoral researcher with the lab, noted that a more comprehensive and adequately funded response is necessary.
Frequently Asked Questions
What temperatures are expected this week?
The National Weather Service forecasts highs in the 90s starting Tuesday, St. Patrick’s Day, with a 10 percent chance of reaching 100 degrees on Thursday, a 50 percent chance on Friday, and a 40 percent chance on Saturday.
When does Clark County consider heat a cause of death?
According to Clark County coroner Melanie Rouse, her office begins to consider heat as a contributing factor in deaths when temperatures reach 95 degrees.
What is the urban heat island effect?
The urban heat island effect is a phenomenon where a lack of trees and green spaces in urban areas traps heat, resulting in significantly higher temperatures in certain neighborhoods, such as downtown Las Vegas, North Las Vegas, the Historic Westside, and East Las Vegas.
As the climate continues to warm, will Southern Nevada be prepared for increasingly frequent and intense heat events?
