Southwest Pacific Ocean

There’s an area of disturbed weather being referred to Remnants of 31P, which is located approximately 268 NM northeast of Darwin, Australia

Animated multi-spectral satellite imagery depicts bursting convection in the northern periphery displaced east of a disorganized llcc. The remnant vortex is tilted eastward with height due to mid-level shear. A microwave image showed scattered and highly disorganized convection.

Environmental analysis shows marginally favorable conditions throughout the area with low to moderate vws (10-15 knots), warm sea surface temperatures, and moderate divergence aloft, but also a lack of strong vertical instability, which has periodically disrupted convective activity. global models are currently in fair agreement on slight potential for regeneration over the next few days.

Maximum sustained surface winds are estimated at 15 to 20 knots.

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