Eastern Pacific teeming with activity as 2 other growing threats emerge behind Tropical Storm Amanda

Invest 91E was designated on Friday, and another area to watch lingers behind it. These systems could become tropical depressions by weekend's end.

The Eastern Pacific is already busy with tropical activity less than a month into hurricane season, as the National Hurricane Center continues monitoring Tropical Storm Amanda as well as two more areas to watch hot on the storm's heels. 

Tropical Storm Amanda is moving west-northwest with winds at 45 mph, according to the National Hurricane Center (NHC).

Sea surface temperatures near Mexico and farther west into the open Pacific are currently running about 2 to 3 degrees above average — favorable conditions for tropical formation.

These temperatures are consistent with a developing super El Niño climate pattern that is expected to play a dominant role this hurricane season, likely increasing tropical activity in the Eastern Pacific, while simultaneously suppressing tropical development in the Atlantic.

The Eastern Pacific averages around 15 named storms, 8 hurricanes and 4 major hurricanes each season.
