A large warm anomaly continues in the Central Pacific centered on  
Howland and Baker Islands.  The region is currently accumulating  
Degree Heating Weeks (HotSpot values >1) and is at Alert Level 1 (DHW  
 >4) throughout the central region of the warming.  Weaker warming  
continues west to South Tarawa.

A small region to the east of Guam is also under Bleaching Warning  
(DHW >0) with positive HotSpot values all around Guam.  However,  
based on our new experimental winds products (soon to be released), a  
large region around Guam is currently experiencing doldrum-like  
conditions that could increase the likelihood of bleaching.

Much of the tropical North Pacific has HotSpot values between 0 and  
1.  This warming is consistent with NOAA observations and forecasts  
that El Nino conditions are developing in the Pacific.
