Pacific Ocean Area of Convection Continues

Area of convection, Pacific Ocean - February 3rd, 2009

Area of convection, Pacific Ocean - February 3rd, 2009

An area of convection has persisted near 13.1S 161.6E, approximately 475 nautical miles northwest of Port-Vila, Vanuatu.

Recent animated multispectral satellite imagery shows deep convection persisting along the northern periphery of a meridionally-elongated low level circulation center (LLCC).

The LLCC lies equatorward of an upper-level anticyclone axis, in an area of strong northward diffluence aloft but moderate vertical windshear.

However, this shear may decrease as the LLCC continues to move poleward toward the upper ridge axis over the next day or two.

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

Minimum sea level pressure is estimated to be near 1003mb.

Because the LLCC is broad and vertical wind shear higher than optimal, the potential for the develpoment of a significant tropical cyclone within thte next 24 hours is poor.
