May 15 is the official start of the hurricane season for the Eastern North Pacific Ocean.  The Sea Surface Temperatures (SSTs) should be cooler than they were in 2015, since the El Niño is dissipating.  That could produce a hurricane season in which the activity is nearer to normal.  In a normal year we might expect 13-17 named storms, 7-10 hurricanes and 3-4 major hurricanes.  Of course, other environmental factors including the location and strength of atmospheric systems will also determine how active the season is.

The National Hurricane Center (NHC) is currently monitoring Invest 90E which is about 950 miles (1530 km) south-southwest of the southern tip of Baja California.  There is a well defined low level circulation in Invest 90E, but there are no deep thunderstorms.  NHC is giving Invest 90E a 20 percent chance of developing into a tropical cyclone during the next five days.
