A rare triple-immersion La Niña seems increasingly likely for the northern hemisphere. The latest forecast from the NOAA Climate Prediction Center, released Thursday, indicates that there is a 62% to 66% chance that La Niña’s current weather condition will persist during the fall and early winter.
If that happens, it will be La Niña’s third consecutive winter, a rare phenomenon we’ve only seen twice since 1950. A third consecutive year for La Niña would likely have a major impact in California.
The climate pattern of La Niña usually divides the country in two, giving a dry winter in the southern half and a wetter winter in the northern half. We don’t know exactly where the dividing line will fall this year. Sometimes La Niña splits California in two, causing heavy rainfall in northern California and drought in southern California.
This year, however, the dividing line was further north. Although parts of Washington and Oregon are out of drought, a dry winter and spring in La Niña have left 99.8% of California suffering from drought conditions.
Another dry winter would be worse news for California than for the rest of the country.
“We have a major and significant drought in the southwest and California and its normal rainy season is winter,” Halpert said. “Here in the Washington, DC area, it usually rains all year round. So if we have a couple of dry months, it’s okay because we can get it back at another time. When you’re in California and the southwest, the 90’s “% of the rain falls in this very short winter and spring season. So if you miss it, you won’t make up for it when you get into summer.”
A worsening drought means more fuel during the peak fire season and could mean more water restrictions.
Other parts of the country, such as the Pacific Northwest, could see more rainfall as a result of a triple La Niña dive. There could also be more rainfall in the midwest and parts of the south later in the winter, specifically in Ohio and the Tennessee Valley.
Will there be an early spring in 2022?
When is the first spring day of 2022? The first day of spring was Sunday, March 20, 2022 at 11:33 a.m. ET. For those of us in the northern hemisphere, this was marked by the arrival of the vernal equinox (also known as the “First Point of Aries”).
What kind of spring is expected for 2022? The spring 2022 season will soon begin, with forecasts revealing that the pattern of current in a jet over the North Pacific and Atlantic will be influenced by the strong polar vortex and the collapse of La Nina.
Will spring come early this year 2022?
Those looking forward to an early spring this year will achieve their wish. The spring equinox will take place on March 19 across the United States, including Alaska and Hawaii, almost 18 hours before the spring equinox occurred in 2019.

What does the Farmer’s Almanac say about the summer of 2022?
Hot, hot, hot. There is no doubt: this summer time will be remembered as a warm one all over the country. Only in New England and around the Great Lakes will general average temperatures tilt toward “with seasonal heat,” but this is based on an unusually cool air wave coming in September.
What is the summer of 2022 going to be like?
Much of the United States is expected to see a warmer summer than typical in 2022. This is especially the case from the Rockies and Plains to the Midwest. An early monsoon can bring some relief to the southwestern desert.
Does La Niña mean cold summer?
La Niña usually means: cooler daytime temperatures (south of the tropics) warmer nighttime temperatures (north)
How does La Niña affect summer? La Niña usually brings drier conditions to the southern half of the country and more rainfall to the pockets of the northern half. Drought conditions often get worse, and it looks like this summer will be the case for most of the West. The only exception is southern Arizona, which can see an active monsoon season.
Does La Niña mean colder weather?
So what is La Niña? The meaning of “girl” in Spanish La Niña simply refers to “a cold event.” During a year of La Niña, winter temperatures are warmer than average in the south and cooler than normal in the north.
Does La Niña make winter warmer?
According to NOAA, La Niña’s biggest impact on rain, snow and US temperatures is usually felt during the winter. In general, La Niña winters are usually drier and warmer than normal in the southern United States and colder and wetter in the northern United States and Canada.
Is La Niña warming or cooling?
La Niña is a climatic pattern that describes the cooling of the surface waters of the ocean along the tropical west coast of South America. La Nina is considered the counterpart of El Nino, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean.
Does La Niña mean a cooler summer?
But first, the conclusion: the summer effects of the Doll are modest, but push the western part of our region to cooler-than-normal conditions. During the La Nina years, sea surface temperatures on the west coast are usually colder than normal, and these cooling effects extend inland.
Does La Niña cause cooling?
The Doll refers to the periodic cooling of ocean surface temperatures in the central and central-eastern equatorial Pacific. Normally, La Nina events occur every 3 or 5 years or so, but can sometimes occur for successive years. The Doll represents the fresh phase of the El Nino / Southern Oscillation (ENSO) cycle.
Is La Niña cold and wet?
Short answer: La Niña is a weather pattern that occurs in the Pacific Ocean. In this pattern, strong winds blow warm water to the surface of the ocean from South America to Indonesia. As warm water moves westward, cold water from the depths rises to the surface near the coast of South America.
Is El Niño or La Niña worse?
Overall, El Niño contributes to more hurricanes in the eastern and central Pacific and fewer hurricanes in the Atlantic, while La Niña contributes to fewer hurricanes in the eastern and central Pacific and more hurricanes in the Atlantic.
Is El Niño getting worse? “The extreme events of El Niño and La Niña may increase in frequency from one every 20 years to one every 10 years at the end of the 21st century under aggressive scenarios of greenhouse gas emissions,” McPhaden said. â € œThe strongest events can also be even stronger than they are today.â €
How is La Niña different than El Niño?
El Niño refers to above-average sea surface temperatures that periodically develop in the central-eastern equatorial Pacific. Represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea surface temperatures in the central-eastern equatorial Pacific.
How El Niño and La Niña similarities and differences?
While an El Niño is an abnormal warming of the central and eastern equatorial Pacific Ocean, a La Niña is an abnormal cooling of the same area. Both patterns usually occur every 3-7 years and play an important role in how warm or cold winter will be in the United States.
How does the climate differ during El Niño and La Niña?
El Niño affects weather systems around the world, causing predictable interruptions in temperature, rain and wind. La Niña is the opposite: an ENSO cooling phase that tends to have global climate impacts as opposed to those of El Niño.
Which is hotter La Niña or El Niño?
In the continental United States, during the El Niño years, winter temperatures are warmer than normal in the mid-north states, and cooler than normal in the southeast and southwest. During a year of La Niña, winter temperatures are warmer than normal in the southeast and cooler than normal in the northwest.
Does El Niño make it hotter?
During an El Niño event, the surface waters of the central and eastern Pacific Ocean become significantly warmer than usual. This change is closely linked to the atmosphere and winds blowing over the vast Pacific.
Is La Niña colder or hotter?
The north and Canada are usually wetter and colder. During La Niña, the waters of the Pacific coast are colder and contain more nutrients than usual. This environment supports more marine life and attracts more cold-water species, such as squid and salmon, to places such as the California coast.
Are we currently in an El Nino or La Niña pattern?
| Winter (November-March) Temperature | Summer (May-September) Temperature |
|---|---|
| Winter (Nov-Mar) Precipitation | Summer (May-September) Rainfall |
Are we in El Nino or La Niña right now? The conditions of La Niña are present. La Niña is likely to continue in the spring of the northern hemisphere (77% chance during March-May 2022) and then the transition to neutral ENSO (56% chance during May-July 2022).
Are we in a La Nina year?
The current forecast favors the continuity of La Niña throughout the summer (59% probability), with a slightly lower probability than autumn (50-55% probability). A third-year La Niña would be quite unusual: we’ve only seen two more since 1950.
Is this year a La Niña year?
The official probabilistic forecast of the ENSO of the CPC / IRI shows that the current La Nina lasts during the summer and until the beginning of the cold season of 2022. It is typical that a new phase arises at the end of summer / autumn with seasonal pressure changes. But for now, it looks like La Nina will likely continue next winter.
Are we still in La Niña?
The La Niña 2021–22 event is over. However, observations and perspectives on the climate model suggest that La Niña could be reformed later in 2022.
Is it El Nino or La Niña 2022?
There are more chances of a third consecutive fall and winter of La Niña in 2022-23. This “triple descent” La Niña has not occurred since 2000. This could have impacts on hurricane season and expansive drought in the west and south.
Are we in an El Nino or La Niña 2022?
Meteorologists from the National Meteorological Service on Thursday released their forecast for the rest of 2022, and right now estimate between 60% and 66% of the chances of a continuous cycle of La Niña during the fall and early winter.
Will 2022 be an El Niño year?
According to the NOAA monthly diagnostic discussion released Thursday, there is an approximately 60% chance that La Niña could stay until February. The blue bars indicate the possibility of La Niña for each three-month period in winter 2022-23, according to this forecast in early May 2022.
