Tropical Depression 27W has formed well to the north-northeast of Guam and northeast of Super Typhoon Francisco. Winds are 25kts currently. Some deep convection has persisted over the LLCC, prompting JTWC to upgrade to a tropical depression. However, the long term future for the depression looks bleak. Shear is increasing due to the outflow from Super Typhoon Francisco, and 27W is forecast to be dragged towards the much larger and stronger cyclone and will probably be absorbed in less than 2 days. Given the increasing shear, significant intensification appears unlikely.

27W remains a sheared tropical depression this evening, with winds of 25kts. The LLCC is almost completely exposed well to the north of the main convective mass. There is quite a lot of convective activity, but not close to the LLCC. Shear continues to affect 27W, in part due to the proximity to Super Typhoon Francisco to the west. As the seperation distance between the two cyclones reduces, 27W is expected to shear apart.

27W has degenerated into a remnant low. The LLCC, if one still exists, is highly stretched. The remnants are headed for even higher shear, so regneration is not expected.
