Joe Knows: What El Nino means for NH

Source: NH1.com

El Nino is here and could get stronger.

El Nino is a phenomenon which occurs irregularly every 2-7 years in the eastern tropical Pacific Ocean in which a warm band of ocean water develops. Sea surface temperatures are warming and weather patterns around the globe are shifting in response. So what does this mean for you?

Strong El Ninos tend to be associated with fewer hurricanes. The Atlantic hurricane season is expected to be quieter than normal, as westerly winds tend to shear off the tops of storms and suppress hurricane development.

With a quieter tornado season so far, that has proven true.

Nationally, there have been just 640 confirmed tornadoes this year, about 300 below below the average.

El Nino have a history of bringing warmer air into the pattern which can help make for warmer winters with more rain than snow, especially across the northern states.
Heavier than normal rain in an active wet pattern could develop in fall to winter period to provide relief for the historic drought in California.

The first half of this year is already been setting records for historic warmth. El Nino will just add more warmth to a warm pattern and will likely push 2015 to be the warmest year on record for the planet.
