Current Tropical Cyclones:

There are no active Tropical Cyclones at the time of this writing

 

Northeast Pacific Ocean:

There are no tropical cyclones nor any areas of disturbed weather under investigation by the National Hurricane Center (NHC)

Central Pacific:

There are no tropical cyclones nor any areas of disturbed weather under investigation by the Central Pacific Hurricane Center (CPHC)

Northwest and Southwest Pacific Ocean, North and South Indian Oceans, and Arabian Sea:

South Indian Ocean

>>> There’s an area of disturbed weather, being referred to as Invest 94S which is located approximately 662 NM north of Learmonth, Australia

Animated enhanced infrared satellite imagery depicts an exposed low-level circulation (llc) with persistent convection south of the llc.

The system is currently in a marginally favorable environment with moderate vertical wind shear (20 knots) and warm sea surface temperatures.

Global models are in good agreement that 94S will track east-southeastward with slow intensification.

Maximum sustained surface winds are estimated at 20 to 25 knots.

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

North Indian Ocean

>>> There’s an area of disturbed weather, being referred to as Invest 94B which is located approximately 154 NM east-southeast of Chennai, India.

Animated enhanced infrared satellite imagery depicts flaring deep convection sheared over the western periphery of a broad low-level circulation center (llcc). A microwave image reveals a very elongated, weakly defined llcc and a cluster of disorganized deep convection over the northwest quadrant.

Environmental conditions are marginally favorable with moderate (20 knot) easterly vertical wind shear offset by broad diffluence aloft and warm sea surface temperature values.

Global models indicate a slow northwestward track over the next two days with slow development due to sustained marginal conditions and dry air entrainment.

Maximum sustained surface winds are estimated at 20 to 25 knots.

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