Animated multi-spectral satellite imagery depicts a broad low-level circulation (llc) with disorganized convection overhead. Another pass reveals a defined circulation with patches of 20-25 knot gradient winds offset to the north of the llc and weaker 5-10 knot winds elsewhere.

Environmental analysis reveals marginally favorable conditions with strong poleward outflow, low (5-10 knot) vertical wind shear and warm sea surface temperatures offset by dry air entrainment.

Global models are in agreement that the system will have little 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 is low.
