Location of Convection in Pacific - February 2nd, 2009

An area of convection has persisted near 12.9S 161.1E, approximately 640 nautical miles north-northwest of Noumea, New Caledonia.

The main image here shows the area of convection 36 hours ago, when it was located farther east. The image of the globe shows the system’s current location.

Animated METSAT imagery depicts a developing low-level circulation center (LLCC) with flaring deep convection located primarily over the western periphery of the disturbance.

An ASCAT pass shows 10 to 15 knot winds near the center of the tight, but elongated, LLCC.

The system is located in a region of strong, vertical wind which is limiting development at this time.

Maximum sustained surface winds are estimated at 10 to 15 knots. Minimum sea level pressure is estimated to be near 1002mb.

Due to the strong vertical wind shear and lack of persistent convection associated with the LLCC, the potential for the development of a significant tropical cyclone within the next 24 hours is poor.
