An area of disturbed weather in the western Pacific is located approximately 225 NM northeast of Andersen AFB, Guam. This area, circled in orange above, has a medium chance of developing over the next 24-48 hours. The Joint Typhoon Warning Center (JTWC) suggests that a low level circulation is trying to develop. It ha disorganized convection around a broad area of low pressure troughing…although with no improvements in structure over the past six hours.

Surface wind speeds are estimated to be between 10-15 knots (12-17 mph) near the circulation center. Upper level winds are in the light to moderately strong range, along with favorable equator-ward divergence.

Here’s a NOAA satellite image of this area

To the south of the main Hawaiian Islands, light thunderstorm activity continued in the Inter-tropical Convergence Zone (ITCZ). An area of showers and thunderstorms are located about 530 miles south of Hilo, Hawaii…and was associated with a weak center of low pressure. This area, according to the Central Pacific Hurricane Center (CPHC) has a low 10% chance of developing into a tropical cyclone during the next 48 hours.

This area of disturbed weather is being referred to as 94C. Here’s a close-up satellite image, along with what the hurricane models are showing. There is no threat to the Hawaiian Islands at this time. Here’s a view of 94C in relation to the islands.

An area of showers and thunderstorms about 530 miles south of Hilo, Hawaii, was associated with a weak center of low pressure in the intertropical convergence zone. Upper-level winds remained marginally favorable for slow development during the next 48 hours. There is a low chance, 10 percent, of this system becoming a tropical cyclone during the next 48 hours.
