The potential for the development of a significant tropical cyclone within the next 24 hours is low

Eastern North Pacific

The eastern Pacific hurricane season officially ended on November 30. Therefore, the last regularly scheduled tropical weather outlook of the 2015 hurricane season has occurred. Routine issuance of the tropical weather outlook will resume on May 15, 2016. During the off-season, special tropical weather outlooks will be issued as conditions warrant.The Pacific Disaster Center (PDC) will begin coverage of the eastern Pacific again on May 15, 2016.

JTWC Significant Tropical Weather Advisory for the southern Pacific Ocean (Issued Dec 10 2015/06Z):

AN AREA OF CONVECTION HAS PERSISTED NEAR 7.4N 144.3E,
APPROXIMATELY 360 NM SOUTH OF GUAM. ANIMATED INFRARED SATELLITE
IMAGERY SHOWS DEVELOPING CONVECTION BUILDING OVER AN AREA OF REVERSE-
ORIENTED TROUGHING. A RECENT 092344Z ASCAT PASS SUPPORTS WIND SPEEDS
OF 10 TO 15 KNOTS WITHIN THE TROUGH. SEA SURFACE TEMPERATURES ARE
FAVORABLE AT 29 TO 30 CELSIUS, PROVIDING SUPPORT TO FURTHER
DEVELOPMENT. UPPER LEVEL ANALYSIS INDICATES THE DISTURBANCE IS
LOCATED WITHIN AN AXIS OF LOW VERTICAL WIND SHEAR WITH A RECENT
SURGE OF POLEWARD OUTFLOW AS A MID-LATITUDE TROUGH TRACKS TO THE
NORTH OF THE TROUGH. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1008 MB. BASED ON THE IMPROVING DEEP CONVECTION WITH FAVORABLE
SURFACE AND UPPER LEVEL ENVIRONMENT, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
