NASA says 2015's exceptionally intense El Niño will likely get stronger in 2016. Based on satellite images, NASA says this El Niño is shaping up to be as strong as the one from 1997, which may have contributed to the Great Ice Storm of 1998.
NASA says a side-by-side comparison of this year to 1997 shows there's a lot of warm water in the Pacific Ocean. The agency said: "The images show nearly identical, unusually high sea surface heights along the equator in the central and eastern Pacific: the signature of a big and powerful El Niño."
Scientists don't know exactly how El Niño will take shape in the coming months.
NOAA has released an update to its El Niño advisory. This image shows the satellite sea surface temperature departure for the month of October 2015, where orange-red colors are above normal temperatures and are indicative of El Niño. This event is forecast to continue through the winter, likely ranking as one of the top 3 strongest events since 1950, before fading in late spring or early summer. El Niño has already produced significant global impacts, and is expected to affect temperature and precipitation patterns across the United States during the upcoming months. Seasonal outlooks generally favor below-average temperatures and above-median precipitation across the southern tier of the United States, and above-average temperatures and below-median precipitation over the northern tier of the United States.

MAKASSAR, SOUTH SULAWESI, INDONESIA - SEPTEMBER 21: Two girls are seen walk behind of dried up ricefield at Manggara Bombang village, Maros district on September 21, 2015 in Makassar, Indonesia. Indonesia's national disaster management agency has declared that the majority of the country's 34 provinces are experiencing drought caused by the El Nino weather phenomenon, the worst drought in the past five years. The dry season forces villagers to walk long distances to find clean water. (Photo by Agung Parameswara/Getty Images)
NOAA issued an update to the El Niño analysis on September 10, 2015, in which forecasters from the Climate Predication Center say a strong El Niño is in place and likely to peak in late fall/early winter, and gradually weaken through spring 2016. This image shows the satellite-based average sea surface temperature data from the week of August 31 - September 6, 2015. Blue areas are cooler than the 1981-2010 average; red areas are warmer than that historical base period. The large pool of warmer than average temperatures along the equatorial Pacific is indicative of the El Niño conditions. (Photo via NOAA)

A couple tries to cool off from the heat caused by El Nino with water overflowing from a defunct but still watery reservoir called the Wawa dam in Montalban in Rizal, east of Manila on February 21, 2010. El NiÃ±o was expected to dehydrate the Metro Manila area over in the next two months, according to the Philippine Atmospheric Geophysical Astronomical Services Administration (Pagasa). Earlier this month the government warned a possible drought caused by the El Nino weather system could slash Philippines rice yields this year.

Tons of dead fish are seen on the banks of the Solimoes River due the water's low level, November 25, 2009 near Manaquiri, 120Km from Manaus. The dry season, affected by the weather phenomenon EL Nino, is worse this year. According a study from Brazil's universities USP,UNICAMP,UFRJ and Embrapa, the country could lose some USD 3.6 billion over the next 40 years.

Heavy clouds covers Indonesia's capital city of Jakarta on November 29, 2009. The month of November ends the dry season and starts the wet period but the weather bureau anticipates El Nino's dry spell to affect Indonesian weather.
