The seventh named storm and fourth typhoon of the season, Imbudo formed on July 15 to the east of the Philippines.

The typhoon made landfall on northern Luzon near peak intensity on July 22, but quickly weakened over land.

In the Philippines, Imbudo was the strongest typhoon in five years, causing widespread flooding and power outages in the Cagayan Valley for weeks.

[3] The next day, the Joint Typhoon Warning Center (JTWC)[nb 5] issued a tropical cyclone formation alert (TCFA), noting that outflow had increased due to an upper-level low to the northeast.

With warm waters and favorable upper-level conditions, the depression quickly organized,[5] and the JMA upgraded it to Tropical Storm Imbudo on July 17.

An increase in outflow to the south and to the north from a tropical upper tropospheric trough (TUTT) caused a 36‑hour period of rapid development beginning on July 19.

[2] Imbudo maintained peak winds for about 12 hours,[3] before the innermost eye contracted to a diameter of 11 km (6.8 mi) in the midst of an eyewall replacement cycle.

[2] At 0300 UTC on July 22, Imbudo struck northern Luzon, with 1 minute winds estimated at 205 km/h (127 mph) by the JTWC.

[6] It was the strongest to hit the province since Typhoon Sally in 1996,[7] striking China with 10 minute winds of 140 km/h (87 mph), as estimated by the JMA.

[8] PAGASA issued a number 4 warning signal, the highest level, for three northern provinces, indicating the imminent threat of a powerful storm.

[9] Despite the warning, a post-storm survey in Isabela province indicated that 34% were unaware of the storm's arrival, while others believed the typhoon would not be as strong.

[11] On July 22 before the storm struck, the Philippine military was put on red alert, increasing security at the presidential palace.

[13] The Hong Kong Observatory issued a number 8 warning signal, indicating the potential for gale-force winds within the territory.

[19] Damage was heavy in the region, totaling P2.2 billion (PHP, $40 million USD)[nb 6], and over 80,000 people were displaced by the storm.

[10] The high damage caused the gross regional product, or overall economy of the Cagayan Valley, to decrease by 0.3% than what would have happened without the typhoon.

[20] Power outages affected Metro Manila, and several billboards were damaged in the city, although there was minimal flooding in the capital.

Adverse conditions caused the Manila Light Rail Transit System Line 1 to close for two hours, stranding hundreds.

[11] Landslides blocked a national highway in Nueva Ecija with debris and fallen trees, which were quickly cleared within a few days.

[25] Before Imbudo struck mainland China, it passed south of Taiwan, dropping heavy rainfall reaching 137 mm (5.4 in) in Taitung County.

[27] At its final landfall in Guangdong, Imbudo produced strong winds, with a peak gust of 200 km/h (120 mph) measured at Shangchuan Island.

[6] Immediately after the storm, the Philippine Air Force were mobilized to help deliver supplies and aid in search and rescue missions.

[11] On July 24, President Gloria Macapagal Arroyo declared that the National Disaster Coordinating Council would provide assistance to citizens affected by the typhoon.

[18] The government ultimately spent about P24 million (PHP, US$435,000)[nb 6] in emergency aid for relocating storm victims, search and rescue operations, and assistance.

In the town of San Mariano in Isabela province, most farmers incurred more debt and continued their same general farming practice, despite sustaining heavy losses from the storm.
