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 the Remnants of TC 05S (Darian)…which is located approximately 910 NM southeast of Port Louis, Mauritius

Animated multi-spectral satellite imagery depicts an exposed, broad low-level circulation with cold-air stratocumulus wrapping into the center and isolated deep convection flaring to the south-southeast.

Based on the available data, 05S is currently assessed as a subtropical cyclone but is expected to transition into an extra-tropical cyclone over the next 24 to 36 hours as it accelerates into the mid-latitude westerlies.

The potential for for transition into a significant tropical cyclone with the next 24 hours is low.

 

Southwest Pacific Ocean

>>> There’s an area of disturbed weather, being referred to as Invest 91P…which is located approximately 173 NM southeast of Noumea, New Caledonia

The system is currently classified as a subtropical storm, generally characterized as having both tropical and mid-latitude cyclone features.

Animated multi-spectral satellite imagery depicts a very broad low-level circulation with isolated convection flaring over the southern quadrant.

Invest 91P is located under a northerly subtropical jet stream with 40-50 knots of vertical wind shear.

Global models indicate a meandering southward track with persistent unfavorable conditions.

Maximum sustained surface winds are estimated at 30 to 35 knots.

The potential for the development remains low.
