. It remained far away from any land masses when it travelled over part of the North Pacific Ocean in August 2005.
identified an area of convection about 870 miles (1,400.1 km) east of Iwo Jima
that had a minimum pressure of 1010 mb. At that time, there was increasing thunderstorm activity around a weak lower level center (LLC). Due to that reason, the possibility for the system to become a tropical cyclone at that time was set at "Poor".. Later, on August 19 the JTWC upgraded the chance that the system could become a tropical cyclone in the next 24 hours to "Fair" because that there was more thunderstorm activity and that the storm was in an area of low to moderate wind shear. That evening, a Tropical Cyclone Formation Alert
was issued due to a strong LLC. At this time, the storm had winds of 25 to 30 mph (11.2 to 13.4 ) and a pressure of 1004 mbar (hPa).. The next day, the storm slowly consolidated and the Japan Meteorological Agency
upgraded the low pressure system to a tropical depression at 0000 UTC on August 20. At that time, the JMA considered the system to have a pressure of 1010 hPa.
At noon of this day, the JTWC designated the area of low pressure as Tropical Depression 12W.
The storm remained at this strength until August 21. Very early that morning, the JTWC upgraded the depression to a tropical storm while the storm was 475 miles (764.4 km) east of Iwo Jima.. Just 3 hours later, the JMA upgraded the storm to Tropical Storm Guchol (see Naming). On August 22, the JMA upgraded the storm to a severe tropical storm and Guchol reached its peak intensity. On August 23, Guchol reached its peak intensity according to the JTWC.. Guchol held its peak strength until August 25 when it was downgraded to a tropical storm by the JMA. Guchol became an extratropical low 6 hours later. The JTWC had issued their final advisory the day earlier.
for use from January 1, 2000 and is the Yapese
