Hurricane Henriette, located a little over 1,770km (~1100 miles) east of Hawaii, was still intense with winds of 90kts (~103.5 mph) this morning. The National Hurricane Center (NHC) predicts that Henriette will weaken tomorrow as it moves over cooler waters and encounters west-southwesterly wind shear.

Henriette's track was overlaid on a Sea Surface Temperature (SST) analysis that was derived from observations by the TRMM Microwave Imager (TMI) radiometer.

 

Sea Surface temperatures have to be warmer than 26 °C for tropical cyclones to survive and this analysis indicates that hurricane Henriette's predicted track will take it briefly over cooler waters with temperatures lower than 24°C. This TMI SST analysis is a subset of one that encompasses the seven day period from July 28 to August 3, 2013 and covers the globe from 40°South to 40°North at a pixel resolution of 0.25° (~25 km).
