Post-Tropical Cyclone 11E JovaLast Advisory


According to the NHC Advisory number 25

The post-tropical cyclone is moving toward the northwest near 6 mph (9 km/h). A gradual turn toward the west and west-southwest is expected over the next couple of days.

Maximum sustained winds have decreased to near 35 mph (55 km/h) with
higher gusts. Jova has become a remnant low and will continue to
gradually spin down.

Central North Pacific…

There are no tropical cyclones, nor any areas of disturbed weather under investigation by the CPHC.

Western Pacific, Indian Ocean and adjacent Seas:

Western Pacific…

>>> There’s an area of disturbed weather being referred to as Invest 90W…which is located approximately 220 NM west-northwest of Guam

Animated enhanced infrared satellite imagery depicts disorganized flaring convection with a poorly defined low level circulation center.

Environmental analysis indicates that 90W is in a marginally favorable environment for development with weak divergence aloft offset by low (10-15 knot) vertical wind shear and warm sea surface temperatures.

Global models show that 90W will travel northeastward over the next 48 hours with weak development.

Maximum sustained surface winds are estimated at 10 to 15 knots.

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