NOAA ENSO December 2024 Update: Weak La Niña Forecast Packs Surprising Punch This post first appeared on the climate.gov ENSO blog and was written by Nat Johnson Although it’s taking its sweet old time to get going, a weak La Niña, the cool phase of the El Niño/Southern Oscillation (ENSO), is expected to develop this winter. Much like I did last November, I thought it would be a good time to delve into how these expected tropical […] Weather WeatherBrains | December 11, 2024 0 Comments
Weak La Niña Poised to Influence U.S. Winter Precipitation Patterns The National Oceanic and Atmospheric Association (NOAA) has shared on its ENSO blog that a weak La Niña, the cooler phase of the El Niño-Southern Oscillation (ENSO), is expected to develop this winter, shifting North America’s precipitation patterns. Contributors he ENSO blog are, amongst others, Michelle L’Heureux (NOAA Climate Prediction Center), Emily Becker (University of Miami/CIMAS), Nat Johnson (NOAA Geophysical […] Industry News SnowBrains | December 5, 2024 0 Comments
NOAA November 2024 ENSO Update: 57% Chance Weak La Niña Will Develop Soon Then Last Through Winter This post first appeared on the climate.gov ENSO blog and was written by Emily Becker. There’s a 57% chance La Niña will develop soon. This is late for La Niña to arrive, and it’s very likely to be a weak event at most. However, even a weak event can influence temperature, rain, and snow patterns across the world. Today, we’ll […] Weather WeatherBrains | November 14, 2024 0 Comments
NOAA ENSO Update: La Niña’s Historical Impact – What to Expect for Snow This Winter This article about the impact of La Niña on snow first appeared on the climate.gov ENSO blog and was written by Tom Di Liberto. I’ll cut to the chase. Spooky season is coming to an end, and people are beginning to set their sights on winter. And when it comes to winter, there’s a big, white, abominable “elephant” in the […] Weather WeatherBrains | October 25, 2024 0 Comments
NOAA ENSO October 2024 Update: Confidence of La Niña Emerging This Winter Decreased to 60% Chance This ENSO update first appeared on the climate.gov ENSO Blog and was written by Emily Becker. The tropical Pacific Ocean reflected neutral conditions—neither El Niño nor La Niña—in September. Forecasters continue to favor La Niña later this year, with an approximately 60% chance it will develop in September–November. The probability of La Niña is a bit lower than last month, […] Weather WeatherBrains | October 10, 2024 0 Comments
NOAA ENSO May 2024 Update: 69% Chance Weakening El Niño Will Transition to La Niña by Fall El Niño weakened substantially over the past month, and we think a transition to neutral conditions is imminent. There’s a 69% chance that La Niña will develop by July–September (and nearly 50-50 odds by June-August). Let’s kick off the ENSO Blog’s tin anniversary with our 121st ENSO outlook update! Attention! First things first: our beloved editor, Rebecca Lindsey, has trained […] Weather WeatherBrains | May 9, 2024 0 Comments
NOAA ENSO Update April 2024: 85% Chance La Niña Develops Next Winter The El Niño of 2023–24 is weakening. Forecasters estimate an 85% chance that El Niño will end and the tropical Pacific will transition to neutral conditions by the April–June period. There’s a 60% chance that La Niña will develop by June–August. Overall, the forecast this month is very similar to last month, and we continue to expect La Niña for […] Weather WeatherBrains | April 12, 2024 0 Comments
NOAA ENSO January 2024 Update: El Niño Reaching Peak Strength | 60% Chance of La Niña in Late-Summer/Fall El Niño is very likely close to peak strength and is likely to continue for the next few months while gradually weakening. Despite the expected weakening of El Niño’s tropical Pacific sea surface signature, impacts to global climate will continue for the next few months. Forecasters currently expect ENSO-neutral conditions (ENSO = El Niño/Southern Oscillation, the whole El Niño & […] Weather WeatherBrains | January 12, 2024 0 Comments
