The system brought down trees; the northeast Philippines experienced strong winds and heavy rains, leaving motorists stranded on several roads and expressways.

The typhoon hit Okinawa, Japan with 41 inches of rain, flooding the small island and injuring 37 people in a 30-hour period.

The system then steadily drifted west, nearing Taiwan and prompting emergency warnings and high alerts; however, the storm missed the island.

[1] The system drifted to the west, and on 25 July the Joint Typhoon Warning Center (JTWC) upgraded the low-pressure area to a tropical depression.

[11] After weakening to a tropical storm, Muifa made landfall at the estuary of the Yalu River on 8 August and the JTWC issued its final warning.

[12] On 5 August, China Airlines cancelled several flights to Okinawa as the storm passed within 45 nautical miles (83 km) of the island.

[16] On 6 August the CWB lifted the sea warning for Taiwan, since the system had turned northwest and was no longer expected to cause any damage to the island.

[21] PRC officials declared that the system was the strongest that year to date to impact the nation, as it passed Taiwan maintaining typhoon strength.

[23] Millions of people living along the coast were ordered to stay indoors, and several hundred flights were cancelled as the typhoon was expected to be the worst to affect China's commercial centre since 2005.

[31] As the system neared land, the Shanghai government urged residents to stay indoors with first-aid kits and emergency supplies.

[32] A message from the federal government of the United States to Americans living in China advised them to "stock up on emergency supplies of food, water, and cash in case of storm-related power outages".

According to a situation report by the National Disaster Risk Reduction and Management Council (NDRRMC), the typhoon killed four people and caused damage worth US$59,203.

[43] On 7 August, as the typhoon brushed the coast of Shanghai, a major sea bridge linking the urban area to an outlying island was closed.
