Meteorological history

Early on July 17, the JMA reported that a tropical depression had developed about 220 km (135 mi) to the northeast of Manila, Philippines. Later that day the JTWC reported that the depression had a small low level circulation center with deep convection flaring to the northeast of the center. However as the low level circulation center was located close to land and was not very organized, the JTWC declared that there was a poor chance of it becoming a significant tropical cyclone within 48 hours. However during that day, the depression rapidly consolidated with an anticyclone helping to develop the low level circulation center. As a result early the next day the JTWC issued a tropical cyclone formation alert on the depression, however they thought that further development might be hindered as it was located close to land. Whilst it moved along the southern edge of the subtropical ridge, the Depression made landfall on Aurora province at 0600 UTC, before the JTWC initiated advisories later that morning, as the low level circulation center had consolidated and poleward outflow into the tropical upper tropospheric trough had improved. Late on July 19, PAGASA issued their last advisory on Tropical Storm Caloy as it had moved out of their Area of Responsibility.. Throughout Aurora, heavy rains triggered flash flooding which destroyed at least one home and stranded hundreds of residents. The Paltic barangay
