El Niño and La Niña affect not only ocean temperatures but also how much it rains on land. The last La Nina appeared during the winter of 2017-2018 and El Nino followed in 2018-2019. There is unusually low air pressure over the western tropical pacific.

This years La Niña event is reaching its apex and NOAA just announced that we will see similar conditions. The La Nina weather system over summer is typically associated with greater rainfall more tropical cyclones and cooler than average temperatures in the Pacific Ocean region. Above normal rainfall is expected in most areas of the country during the.

The change is as a result of the atmosphere and the winds blowing over the vast Pacific. The North and Canada tend to be wetter and colder. What is expected to happen to.
