Krovanh's predecessor can be traced back to an area of disturbed weather just west of the Marshall Islands on August 30, which then developed to a tropical depression two days later. It moved north to the northeast, and gradually shifted to the west in track. Gradually intensifying, Krovanh underwent a period of rapid deepening and explosively intensified from a Category 1 typhoon to a Category 4 super typhoon within 19 hours. Krovanh entered an area of moderate amounts of wind shear, and weakened to a Category 3 later that day, but Krovanh still attained a stadium effect. The next day, however, Krovanh re-intensified, and achieved it's title as a Category 5 super typhoon just to the south of Guam.
Krovanh maintained it's intensity and explosively intensified further. It's pressure dropped a whopping 31 mbars in just 16 hours. As the typhoon slowed down and shifted to the north, Krovanh attained a peak intensity with winds of up to 175 knots (325 km/h; 200 mph) with a pressure reading of 869 millibars, thus making it the strongest typhoon in terms of pressure, until beaten by Choi-wan two months later. On 932 EDT, the relentless storm moved ashore over Baras, Catanduanes at peak intensity. Making it's second landfall at San Jose, Camarines Sur, and making several other landfalls over different parts of Luzon.
Meteorological historyKrovanh's predecessor can be traced back to an area of disturbed weather spotted by the Joint Typhoon Warning Center (JTWC) on August 30, over an area of extremely favorable conditions just south of the Marshall Islands. It became a tropical disturbance the following day, as Japan Meteorological Agency (JMA) started to monitor the disturbance. On September 1, the disturbance was given a Tropical Cyclone Formation Alert by JTWC and was classified by JMA to be a Tropical Depression, as the system steadily organized. About an hour later, it was designated by the JTWC as 21W. On the 2nd of September, 21W has been upgraded to a tropical storm by JMA, as the JTWC followed suit. The tropical storm was assigned the name Krovanh. Krovanh executed a generally western track, as the storm was in the extreme southern periphery of s subtropical ridge. Krovanh's intensification halted for 24 hours due to lack of upper-level divergence and dry air. As Krovanh maintained steady equatorial flow and organization, JMA prompted to upgrade Krovanh to a severe tropical storm. A day later, JMA upgraded Krovanh directly to a typhoon, as the storm showed a very efficient and imminent central dense overcast. A small, pinhole eye appeared at the center of the storm, as JTWC followed suit. The ridge weakened as the typhoon moved generally to the northwest. As it intensified further, JTWC upgraded the typhoon to a Category 2 in 16 hours, while JMA followed suit. The typhoon's eye drastically improved and widened; the convection over it's central dense overcast cooled dramatically, which prompted JTWC to upgrade it to a Category 4 typhoon, and soon a Category 5 super typhoon just south of Guam.
