[1] Gradually, the disturbance became more organized as it moved through an area of moderate wind shear, high sea surface temperatures (estimated at 29 to 30 °C (84 to 86 °F) by satellites) and favorable diffluence.

[2] Further development of the low prompted the Joint Typhoon Warning Center (JTWC) to issue a Tropical Cyclone Formation Alert on June 20.

[5] A large system, roughly 1,480 km (920 mi) wide, convection was slow to consolidate over the center which remained mostly cloud free.

Due to its large size, slow intensification was expected over the following several days as the storm tracked generally northwestward towards Taiwan.

[3] Later that day, the storm's expansive windfield began to contract as an upper-level trough near Taiwan impinged on the western edge of Meari.

Though the storm's overall structure degraded somewhat, surface observations continued to show intensification with a meteorological station on Shimojishima reporting winds of 124 km/h (77 mph).

[9] Late on June 24, Tropical Storm Meari is estimated to have attained its peak intensity with winds around 110 km/h (70 mph) and a barometric pressure of 975 mbar (hPa; 28.79 inHg).

[11] Throughout June 25, Meari's structure rapidly degraded as an approaching trough produced major subsidence over the northwestern portion of the storm.

[15] After remaining near the peninsula for several hours, Meari rapidly accelerated towards the northeast and began taking on characteristics of an extratropical cyclone.

[16] Early on June 27, the storm completed the transition into an extratropical system hours before striking North Korea near the city of Anju with winds of 85 km/h (50 mph).

[3] Following the first advisory on Tropical Depression Falcon by PAGASA on June 21, emergency management officials in the Philippines began taking precautions for potential damage.

Multiple emergency management agencies across the country stockpiled resources and placed relief teams on standby to quickly assist residents affected by the storm.

[22] Along the Nakdong River in North Gyeongsang, a 100 m (330 ft) section of bridge in Chilgok, built in honor of soldiers killed during the Korean War, collapsed.

With many residents stranded by flood waters, multiple branches of the Philippine military provided rescue vehicles, such as trucks and rubber boats, to local authorities.

[33] In the wake of widespread flooding, South Korean President Lee Myung-bak expressed his sadness over the loss of life from Meari.

[34] By early August, the Government of North Korea began a relief operation to assist residents affected by the July floods and Tropical Storm Meari.

The proposed aid included 5 billion won ($4.7 million USD) worth of quilts, medicine, instant noodles and healthy meals; however, the request made by the North Korean government was for rice and cement.
