the west, late on October 22. Namtheun's extratropical remnant brought heavy rain and powerful winds to the Pacific Northwest. Typhoon Malou On October 20, the JTWC noted an area of convection approximately east of Guam. Infrared satellite imagery found that it formed a flaring convection which was displaced to the northwest from the actual center, but at 06:00 UTC the next day, the JTWC discontinued giving advisories to the area of convection, as its convection had completely dissipated. On the same day at 18:00 UTC, the JMA recognized the same area of convection, as a low pressure area. At 15:00 UTC of October 22, the JTWC started giving advisories for the area of convection as it developed sufficient convection and a poorly defined low-level circulation. On the next day at 18:00 UTC, the JMA upgraded it to a tropical depression, and three and a half hour later, the JTWC issued a TCFA. At 03:00 UTC of October 24, the JTWC upgraded to a tropical depression and designated as 25W. Later at 18:00 UTC, the JTWC upgraded it to a tropical storm, as the organization of the convection had increased. Six hours later, the JMA did the same thing and named it Malou. At midday of the next day, the JMA upgraded it to a severe tropical storm. Early on October 27, the JTWC upgraded it to a Category 1-equivalent typhoon, as it developed an eye-like feature wrapped around a ragged spiral bandings. At 18:00 UTC the same day, the JMA upgraded it to a typhoon. Tropical Depression 26W At 00:00 UTC of October 22, the JMA noted the formation of a low-pressure area east of Mindanao. Two days later at 06:00 UTC, the JMA upgraded it to a tropical depression as it was located off the coast of the island of Palawan. On the same day, the JTWC noted the same low pressure area and gave a low chance of formation, which was later upgraded to medium. At 05:30 UTC of October 25, the JTWC issued a TCFA for the system, as its convection had improved and developed a weakly defined LLCC. On the next day, after re-issuing the TCFA at 05:00 UTC, the JTWC upgraded it to a tropical depression at 09:00 UTC as it was located off the coast of Vietnam. Satellite imagery found that its LLCC had become defined however the convective structure continued to remain disorganized.
