A natural weather pattern called El Niño has now started, US scientists have announced. This event is known for its influence on global weather patterns.

El Niño typically causes warmer ocean waters in the Pacific Ocean. This change can lead to significant shifts in weather around the world.

Scientists warn that the start of El Niño increases the risk of weather extremes. These can include more intense heatwaves, droughts, and heavy rainfall in different regions.

The pattern is also expected to contribute to an overall rise in global temperatures. This year's El Niño is predicted to be a strong one.

The effects of El Niño can vary greatly by location. Some areas may experience severe dry spells while others face flooding.

Authorities are monitoring the situation closely. They advise citizens to stay informed about weather forecasts and advisories.

Understanding these natural weather cycles is crucial for preparing for their impacts. El Niño is a key factor influencing climate year to year.
