Points of the compass
Directional divisions marked on a compass
The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal...
West
One of the four cardinal directions
West is one of the four cardinal directions or points of the compass. It is the opposite direction from east and is the direction in which the Sun sets on the Earth.

Why It Matters
This heat wave matters because it poses immediate health risks to millions of residents across the Southwest and West, particularly vulnerable populations like the elderly, children, and outdoor workers. It strains energy grids during peak cooling demand, increasing blackout risks and electricity costs. The event also highlights accelerating climate change impacts, as such extreme heat events become more frequent, intense, and prolonged, affecting agriculture, water resources, and emergency services.
Context & Background
- The Southwest and Western U.S. have experienced increasingly severe heat waves over the past decade, with 2023 being one of the hottest years on record globally.
- Urban areas like Phoenix, Las Vegas, and Los Angeles are particularly vulnerable due to the urban heat island effect, which amplifies temperatures.
- Heat-related illnesses cause hundreds of deaths annually in the U.S., with the CDC noting that extreme heat is the deadliest weather-related hazard.
What Happens Next
In the short term, expect continued high temperatures with potential heat advisories and warnings, leading to increased emergency room visits and possible power outages. Over the next weeks, monsoon moisture may bring some relief but also risk of flash floods in arid regions. Long-term, climate models predict more frequent and intense heat waves, prompting cities to update heat action plans and infrastructure.
Frequently Asked Questions
The Southwest and Western U.S., including states like Arizona, Nevada, California, and Texas, are experiencing the brunt of the heat, with cities such as Phoenix and Las Vegas setting record highs. These regions are prone to extreme heat due to their arid climates and urban development.
Stay indoors during peak heat hours, use air conditioning or cooling centers, drink plenty of water, and avoid strenuous outdoor activities. Check on vulnerable neighbors, and never leave children or pets in vehicles, as temperatures can rise dangerously fast.
Yes, scientists attribute the increasing frequency and intensity of heat waves to human-caused climate change. Rising global temperatures from greenhouse gas emissions make such extreme events more likely, as seen in recent studies on heat trends in the U.S.
