Las Vegas Ends 214-Day Dry Spell with 0.01 Inch of Rainfall

Las Vegas – After a staggering 214 days without any measurable rainfall, the Las Vegas Valley finally saw some drizzle.

On Thursday, the National Weather Service recorded 0.01 inch of rain at Harry Reed International Airport, ending one of the longest dry spells in the city’s history.

This marks the first time in 88 years that Las Vegas has gone more than 200 days without rain, according to the National Weather Service. The last significant rainfall in the area was seven months ago, before July 13th, 2024.

While this dry spell broke records, the city’s longest stretch without measurable rain remains at 240 days, a drought that occurred in 2020.

The current winter season is uncharacteristically warm and dry in the region.

Almost all of southern Nevada is currently facing “extreme” drought conditions. The US drought monitors release color-coded maps weekly to show the severity of drought conditions nationally.

The most recent drought monitor map shows that over 88% of the state is experiencing some level of drought, with around 21% facing “extreme” or “exceptional” dryness.

Thursday’s rain extended across desert areas in the southwest, affecting much of southern Nevada, as well as parts of California and Arizona.

The Las Vegas branch of the Meteorological Bureau stated that due to months of dry weather, the exact amount of rainfall from this event remains uncertain. According to x.

Higher elevations are expecting snow, with winter storm warnings in place for Nevada’s Spring Mountain area until Friday afternoon. Weather services predict 12-24 inches of snow in the mountains, with snowfall potentially reaching above 8,000 feet.

The precipitation is part of a storm system moving through southern Nevada on Thursday and Friday.

The Weather Service forecasts Las Vegas could receive 0.5-0.9 inches of rain over the two days.

Solar Phenomena Cast a Spell on Canadian Skies

December 17, 2023

Increased solar activity has led to widespread aurora borealis across Canada.

A surge in solar activity in mid-December 2023 caused energetic particles to collide with Earth’s magnetosphere, creating rippling auroras across Earth’s northern latitudes. VIIRS (Visible Infrared Imaging Radiometer Suite)

The Suomi NPP satellite captured this image of light from the aurora borealis over western Canada in the early morning hours of December 17, 2023. VIIRS’s day/night band detects nighttime light at wavelengths ranging from green to near-infrared, using filtering techniques to observe signals such as city lights, moonlight reflections, and the aurora borealis.

Origin of the aurora borealis

These auroras may have resulted from several coronal mass ejections.

Increased solar activity

Solar activity is increasing as we approach the peak of solar cycle 25, which is predicted to occur on or around the year 25.
July 2025. The Sun’s magnetic field reverses at the peak of these cycles, and each cycle lasts about 11 years. Scientists track fluctuations in solar activity by monitoring the number and location of sunspots, the dark spots on the sun’s surface that are the main cause of solar eruptions.

Relationship between aurora and solar flares

The aurora seen here occurred several days after the aurora borealis.
strongest solar flare How has this solar cycle been so far? While coronal mass ejections take days to reach Earth, solar flares can reach Earth in minutes and disrupt radio communications. Coronal mass ejections often, but not always, occur in parallel with solar flares.
