:Tropical Storm Faxai (2007)

{{storm path|Faxai 2007 track.png| alt=Tracking map of tropical storm}}

Tropical Storm Faxai began as an area of convection that persisted about {{convert|805|km|sp=us}} west of Guam on October 24. Satellite imagery indicated broad cyclonic turning in the lower levels of the atmosphere, and a trough was near the surface. Convection consolidated around the center of the low-level circulation, and the upper-level environment—low wind shear and good divergence—favored development.{{cite web|publisher=Joint Typhoon Warning Center|date=October 24, 2007|access-date=March 2, 2009|title=Significant Tropical Weather Advisory for the Western and South Pacific Oceans|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/GuamStuff/2007102415-ABPW.PGTW}}{{dead link|date=September 2017 |bot=InternetArchiveBot |fix-attempted=yes }} The following day, the Japan Meteorological Agency (JMA) classified the system as a tropical depression.{{cite web|publisher=Japan Meteorological Agency|year=2008|access-date=March 2, 2009|title=JMA Annual Tropical Cyclone Report for 2007|url=http://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/AnnualReport/2007/Text/Text2007.pdf|archive-url=https://web.archive.org/web/20131212234000/http://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/AnnualReport/2007/Text/Text2007.pdf|archive-date=December 12, 2013|url-status=live}} Shortly after, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert as convection deepened around a partially exposed low. The storm traveled northwest under the influences of a subtropical ridge to the north.{{cite web|publisher=Joint Typhoon Warning Center|date=October 25, 2007|access-date=March 2, 2009|title=TCWC Advisories for October 25, 2007 at 12Z|url=http://www.weather.unisys.com/hurricane/archive/07102512|archive-url=https://web.archive.org/web/20131005041245/http://weather.unisys.com/hurricane/archive/07102512|archive-date=October 5, 2013|url-status=dead|df=mdy-all}} At 0000 UTC on October 26, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) designated the system as a tropical depression and gave it the local name Juaning. Around the same time, the JMA upgraded the depression to a tropical storm and gave it the name Faxai.

The JTWC issued advisories on Faxai, designating it as 20W; however, they classified it as a tropical depression.{{cite web|publisher=Joint Typhoon Warning Center|date=October 26, 2007|access-date=March 2, 2009|title=TCWC Advisories for October 26, 2007 at 00Z|url=http://www.weather.unisys.com/hurricane/archive/07102600|archive-url=https://web.archive.org/web/20131005041307/http://weather.unisys.com/hurricane/archive/07102600|archive-date=October 5, 2013|url-status=dead|df=mdy-all}} Several hours later, the storm began to undergo an extratropical transition, with convection persisting mainly in the northwestern portion of the storm and cold, dry air entering into the southwestern portion.{{cite web|publisher=Joint Typhoon Warning Center|date=October 26, 2007|access-date=March 2, 2009|title=TCWC Advisories for October 26, 2007 at 06Z|url=http://www.weather.unisys.com/hurricane/archive/07102606|archive-url=https://web.archive.org/web/20131005041318/http://weather.unisys.com/hurricane/archive/07102606|archive-date=October 5, 2013|url-status=dead|df=mdy-all}} At 1200 UTC, PAGASA issued their final advisory on Tropical Storm Juaning as it moved out of their area of responsibility.{{cite web|author=Philippine Atmospheric, Geophysical and Astronomical Services Administration|publisher=Typhoon 2000|date=June 13, 2008|access-date=March 2, 2009|title=PAGASA Tropical Cyclone Warning Log|url=http://www.maybagyo.com/stormarchives/2007/stormlogs/10juaning07_log.htm|author-link=Philippine Atmospheric, Geophysical and Astronomical Services Administration|archive-url=https://web.archive.org/web/20120213153008/http://www.maybagyo.com/stormarchives/2007/stormlogs/10juaning07_log.htm|archive-date=February 13, 2012|url-status=live}} The JTWC reported that Tropical Depression 20W (Faxai) had become extratropical around this time as it merged with a baroclinic zone. A cold front developed along the southern portion of Faxai, a feature of extratropical cyclones.{{cite web|publisher=Joint Typhoon Warning Center|date=October 26, 2007|access-date=March 2, 2009|title=TCWC Advisories for October 26, 2007 at 12Z|url=http://www.weather.unisys.com/hurricane/archive/07102612|archive-url=https://web.archive.org/web/20131005041329/http://weather.unisys.com/hurricane/archive/07102612|archive-date=October 5, 2013|url-status=dead|df=mdy-all}} Around that time, the JMA upgraded Faxai to a severe tropical storm with (10-minute sustained) winds of {{cvt|95|km/h}}.

The JTWC subsequently upgraded the depression to a tropical storm based on the development of a very impactful central dense overcast. A shortwave trough over the Korean peninsula provided a favorable upper-level environment for Faxai to intensify.{{cite web|publisher=Joint Typhoon Warning Center|date=October 26, 2007|access-date=March 2, 2009|title=TCWC Advisories for October 26, 2007 at 18Z|url=http://www.weather.unisys.com/hurricane/archive/07102618|archive-url=https://web.archive.org/web/20131005041340/http://weather.unisys.com/hurricane/archive/07102618|archive-date=October 5, 2013|url-status=dead|df=mdy-all}} Early the next day, Faxai began accelerating rapidly towards the northeast in the mid-latitude westerlies. An anticyclone over Japan created a strong pressure gradient between it and the tropical storm, causing the wind field of Faxai to expand significantly to the northeast. As the JTWC issued their final advisory,{{cite web|publisher=Joint Typhoon Warning Center|date=October 27, 2007|access-date=March 2, 2009|title=TCWC Advisories for October 27, 2007 at 00Z|url=http://www.weather.unisys.com/hurricane/archive/07102700|archive-url=https://web.archive.org/web/20131005041351/http://weather.unisys.com/hurricane/archive/07102700|archive-date=October 5, 2013|url-status=dead|df=mdy-all}} they assessed the storm to have reached its peak intensity, with (one-minute sustained) winds of {{cvt|75|km/h}}.{{cite web|publisher=Joint Typhoon Warning Center|year=2008|access-date=March 2, 2009|title=JTWC Best Track for Tropical Storm 20W (Faxai)|url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/2007/2007s-bwp/bwp202007.txt|archive-url=https://web.archive.org/web/20131005010628/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/2007/2007s-bwp/bwp202007.txt|archive-date=October 5, 2013|url-status=dead}} The JMA also assessed Faxai to have reached its peak intensity at that time, with (10-minute sustained) winds of {{cvt|100|km/h}} and a minimum pressure of 975 hPa (mbar); however, the National Oceanic and Atmospheric Administration (NOAA) reported that Faxai had attained hurricane-force winds by this time, peaking at {{cvt|130|km/h}}.{{cite web|author=George P.

The extratropical remnants persisted for more than a day before dissipating over open waters late on October 28. NOAA, on the other hand, continued to monitor the remnants of Faxai, with the system reaching the Aleutian Islands on October 29. The following day, the storm rapidly intensified, with the central pressure dropping to 957 hPa (mbar) by 1800 UTC. On October 31, the system tracked into Alaska and weakened.

The Japan Meteorological Agency uses 10-minute sustained winds, while the Joint Typhoon Warning Center uses one-minute sustained winds.{{cite web|publisher=Joint Typhoon Warning Center|year=2005|title=Frequently Asked Questions|access-date=July 3, 2009|url=http://www.usno.navy.mil/JTWC/frequently-asked-questions-1|archive-url=https://web.archive.org/web/20130901174657/http://www.usno.navy.mil/JTWC/frequently-asked-questions-1|archive-date=September 1, 2013|url-status=dead}} The conversion factor between the two is 1.14.{{cite web|publisher=United States Navy|year=2009|url=http://www.nrlmry.navy.mil/~chu/chap6/se200.htm|title=Section 2 Intensity Observation and Forecast Errors|access-date=March 8, 2009|archive-url=https://web.archive.org/web/20120830042306/http://www.nrlmry.navy.mil/~chu/chap6/se200.htm|archive-date=August 30, 2012|url-status=dead}} JMA's peak intensity for Faxai was 100 km/h (65 mph) 10-minute sustained, or 120 km/h (75 mph) one-minute sustained.

As Faxai approached Japan, All Nippon Airways canceled all of its day{{discuss}} flights between Tokyo and the Izu Islands. Tokai Kisen, which operates ferries between Tokyo, the Izu Islands and Shizuoka Prefecture, canceled some services due to the storm. Areas around Tokyo were warned of the expected heavy rains, waves up to {{cvt|6|m}}, and high winds.{{cite web|author=Ron Rhodes|publisher=Bloomberg News|date=October 27, 2007|access-date=March 2, 2009|title=Typhoon Faxai Nears Central Japan; Flights Canceled (Update1)|url=https://www.bloomberg.com/apps/news?pid=20601087&sid=ajfFElYhmfWU&refer=home|url-status=dead|archive-url=https://web.archive.org/web/20090123033802/http://www.bloomberg.com/apps/news?pid=20601087|archive-date=January 23, 2009}} Residents were advised to stay indoors during the storm, especially after sunset, and to avoid possible flying debris.{{cite web|author=増田雅昭|publisher=Yahoo Japan Corporation|date=October 27, 2007|access-date=June 10, 2009|script-title=ja:韋駄天（いだてん）台風、接近中|url=http://blogs.yahoo.co.jp/wth_map/50108417.html|language=ja|title=Idaten Typhoon Approaching|archive-url=https://web.archive.org/web/20120222040151/http://blogs.yahoo.co.jp/wth_map/50108417.html|archive-date=February 22, 2012|url-status=live}}

Although Faxai did not make landfall, the outer bands produced heavy rains, which caused minor damage along the eastern coast of Japan. The highest total rainfall was recorded on Miyakejima at {{cvt|458|mm}} and in the Ōshima Subprefecture of Tokyo, {{cvt|192|mm}} was recorded. The rainfall in Miyakejima nearly surpassed the record daily rainfall for October 27.{{cite web|author=Staff Writer|publisher=Earthweek: A Diary of the Planet|date=November 2, 2007|access-date=May 22, 2009|title=Tropical Storm Faxai Drenches Parts of Japan|url=http://www.earthweek.com/online/ew071102/ew071102f.html|archive-url=https://web.archive.org/web/20120214111745/http://www.earthweek.com/online/ew071102/ew071102f.html|archive-date=February 14, 2012|url-status=live}} Rainfall rates peaked at {{cvt|95|mm/h}} on Miyaketsubota,{{cite web|publisher=National Institute of Informatics|year=2007|access-date=March 2, 2009|title=Japan Rainfall for October 25 to 28, 2007|url=http://agora.ex.nii.ac.jp/cgi-bin/dt/summary_prec.pl?id=200720&lang=en&sort=total&order=dec&stype=number|archive-url=https://web.archive.org/web/20190304141209/http://agora.ex.nii.ac.jp/cgi-bin/dt/summary_prec.pl?id=200720&lang=en&sort=total&order=dec&stype=number|archive-date=March 4, 2019|url-status=live}} which triggered seven mudslides throughout the country.
