Information from meteorologists indicates that there is another La Niña event , and this could bring bad news especially for part of the Western United States .

Is the second year in a row that the world is heading towards a new climate event of this type, which would mean dry (still more) western areas of the United States, and would boost (also, more) the season of hurricanes in the Atlantic .

Five months after the end of La Niña –phenomenon started in September of 2020 – the National Office of Oceanic and Atmospheric Administration (NOAA) , informed that another cooling is in process of the Pacific waters .

It contrasts with the warmest El Niño pattern , and means months or even years of changes in the climate of the entire planet; changes with variations depending on the place that can only be analyzed by trends and without any certainty.

For example, the deputy director of the Climate Prevention Center of the NOAA, Mike Halpert , indicated that the possibility that this event is moderate is 57% , against him 15% that is strong . This is based on the fact that in the second year of consecutive events, it is generally of less intensity than the first.

A study indicated that La Niña –which would last until spring – has caused greater are chiases and agricultural damage in the United States, when compared to El Niño.

By regions, what La Niña will bring

For a third of the US in the south and particularly the southwest, the phenomenon will mean more heat and drought . In the west two decades of drought have worsened in the last two years.

To the northwest ( Washington, Oregon and maybe Idaho and Montana ), will bring good chances of rain .

A more wet and cold weather is expected would be in the Ohio Valley and the northern plains, while there could be more snow storms to the north during winter, otherwise the central region of the Atlantic.

As for the world, La Niña tends to cause more rainfall in much of Southeast Asia and northern Australia. The climate will be drier in southeastern China and central Africa.

There will be colder climates in western Canada, southern from Alaska, Japan, the Korean Peninsula, West Africa and Southeast Brazil.
