Western Pacific Ocean

>>> There’s an area of disturbed weather being referred to as Remnants of 01W (Sanvu)…which is located approximately 426 NM east-southeast of Guam

Animated multi-spectral satellite imagery shows a broad, ragged, and partly-exposed low-level circulation (llc) with disorganized convection sheared eastward of the llc.

Environmental analysis reveals marginal conditions with strong poleward outflow, low (5-10 knot) vertical wind shear over the llc and warm sea surface temperatures offset by dry air entrainment and strong (25+ knot) vertical wind shear just 30 NM to the north.

Global models are in agreement that the system will have no significant development as it tracks westward over the next 24-48 hours.

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 remains low.
