Tropical Cyclone 05S (Darian) – Final Warning
According to JTWC Warning number 28, sustained winds were 40 knots, with gusts to 50 knots.
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.
A microwave image indicates shallow banding wrapping tightly into a ragged center with extensive dry air present over the system.
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 36 to 48 hours as it accelerates into the mid-latitude westerlies.
SW 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.
