Invest 99S is in an environment favorable for development, with good outflow aloft, warm sea surface temperatures…and low 10-15 knot wind shear. Global models are in good agreement that invest 99S will track to the west and consolidate over the next several days. Maximum sustained surface winds are estimated at 15-20 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to medium.

Surface observations from the Cocos Islands indicate southerly winds at 27 knots. Invest 90S is in a favorable environment for development with good outflow aloft, moderate 20-25 knot wind shear, and warm sea surface temperatures. Global models are in good agreement that invest 90S will continue to consolidate and track southwestward to the warning threshold…over the next 24-36 hours. Maximum sustained surface winds are estimated at 25-30 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.
