La Niña Expected to Emerge: What It Means
A prediction from National Oceanic and Atmospheric Administration (NOAA)
NOAA reports a potential return of La Niña in the coming months, which could cause a weather pattern shift. This prediction is significant because La Niña is a weather pattern that typically brings cooler-than-average temperatures across the globe, with effects lasting 9 to 12 months.
NOAA predicts a 75% chance of La Niña developing by winter 2023-24, with the effects potentially lasting into early 2024.
What exactly is La Niña?
La Niña is a climate pattern that is characterized by unusually cool ocean temperatures in the central and eastern tropical Pacific Ocean.
How does it affect the weather?
La Niña can disrupt typical weather patterns worldwide. During La Niña, the jet stream often shifts southward, bringing wetter and cooler conditions to the southern and eastern United States, as well as parts of South America and Australia.
Drier conditions may occur in the northern United States and Canada, as well as parts of Southeast Asia.
What are the potential impacts of La Niña this year?
The exact impacts of La Niña can vary, but some potential effects include:
- Increased risk of flooding in the southern and eastern United States, South America, and Australia
- Drought conditions in the northern United States, Canada, and Southeast Asia
- More active hurricane seasons in the Atlantic and Eastern Pacific
- Changes in fish populations and marine ecosystems
Steps to prepare for La Niña
While La Niña can have some negative impacts, there are steps you can take to prepare. These include:
- Staying informed about the latest weather forecasts
- Taking precautions to protect your property from flooding or drought
- Being aware of the potential health risks associated with extreme weather
- Planning for disruptions to travel and other activities
By taking these steps, you can help to reduce the risks associated with La Niña and stay safe during this weather pattern.
