western pacific Tropical Storm 12W

[Somerset Squall]

A tropical depression has formed just off the east coast of Luzon. 12W has winds of 25kts. The depression is not located in a favourable environment. Moderate shear and dry air have left the LLCC partially exposed from the associated convection. As Typhoon Halola approaches from the east, even stronger shear will affect 12W as it gets dragged northeastwards in the wake of Halola. Some slight intensification is forecast, but 12W is forecast to remain a tropical depression until it dissipates in a few days.

12W became a 40kt tropical storm according to JTWC, but has since been sheared apart by the outflow from Tropical Storm Halola to the north. JTWC have issued their last advisory.
