Tropical Cyclone Halong (11W) has passed between Rota and Guam in the Mariana Islands. According to a Stars and Stripes blog, heavy rainfall caused flooding in low-lying areas of Guam, and strong winds downed trees and power lines in several villages resulting in power outages.
Rota was relatively unscathed by TC Halong. Rota’s Mayor Melchor A. Mendiola stated that no flooding was reported in residential areas because neighborhoods are located at a higher elevation than the coastline, in a release by Guam’s Pacific Daily News.
In preparation for the cyclone, the JTWC generated a tropical storm warning for Guam, Tinian and Saipan, and typhoon warning for Rota. Additionally, the National Weather Service (NWS) issued flash flood warnings for Guam and Rota. However, all tropical storm and typhoon warnings have been expired.
TC Halong remains active in the northwestern Pacific Ocean and is tracking west-northwestward. JTWC expects TC Halong to intensify to typhoon status by August 1, as it moves northwestward in the western Pacific.
