Originating from a trough over the open Pacific Ocean on July 29, Francisco developed into a tropical depression on August 1.

In anticipation of Francisco impacting Japan, officials in Kyushu ordered evacuations for coastal residents in and around Miyazaki.

On July 29, 2019, the Joint Typhoon Warning Center (JTWC)[nb 1] began monitoring a trough approximately 695 km (432 mi) north-northwest of Wake Island.

Situated in a region of low wind shear, favorable upper-level outflow, and traversing northwest over warm waters, development into a tropical cyclone over subsequent days was anticipated.

[7][nb 3] Traveling along a general northwest track toward Japan, the system steadily intensified and attained typhoon status around 09:00 UTC on August 5.

[7] Typhoon Francisco reached its peak intensity around 12:00 UTC with ten-minute sustained winds of 130 km/h (80 mph)[nb 4] and a pressure of 970 mbar (hPa; 28.64 inHg).

[12] Once overland, the system greatly weakened to a low-end tropical storm before emerging over the Korea Strait shortly after 06:00 UTC on August 6.

[7] Tropical Storm Francisco made landfall in Busan, South Korea, at 11:20 UTC (8:20 p.m. local time) on August 6.

[13] Less than an hour after landfall, the Korea Meteorological Administration assessed Francisco to have degenerated into a remnant low;[13] however, the JMA and JTWC continued monitoring it as a tropical cyclone.

[26] The United States Navy raised the Tropical Cyclone Condition of Readiness for Fleet Activities Sasebo on August 3.

The combined rains from Danas, Francisco, and Lekima aided in filling Fukuoka Prefecture dam, which reached 81.2 percent capacity.

[43] Ahead of the typhoon's landfall in Kyushu, the system brought strong winds and heavy rain to the southern coast of Shikoku.

[45] Off the coast of Minamibōsō, Chiba, a fishing boat capsized amid rough seas produced by the typhoon on August 5.

[47] Humid air brought north by the typhoon exacerbated the effects of a deadly heat wave in eastern Japan.

[50] In anticipation of the storm's arrival, the Korean Meteorological Agency issued heavy rain warnings for eastern provinces and mountainous areas.

[52] TCCOR levels for Commander Fleet Activities Chinhae were raised beginning on August 5 and remained in place through the duration of the typhoon.

Additional rainfall from Typhoon Lekima and subsequent storms led to flood concerns along the Tumen River in Rason.

[57] Twenty-five North Korean fishing boats seeking to avoid the storm sought refuge in Olga Bay, within Russia's Primorsky Krai.

[58][59] On August 7, the Russian Ministry of Emergencies warned of heavy rains and damaging winds in Primorsky Krai from the remnants of Francisco.

[68] In Vladivostok strong winds downed multiple trees, leaving some neighborhoods without power and damaging cars.
