caption_attribution_description: English: Track map of Typhoon Francisco of the 2019 Pacific typhoon season. The points show the location of the storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir–Simpson scale (see below), and the shape of the data points represent the nature of the storm, according to the legend below.

context_page_description: Typhoon Francisco was a small tropical cyclone that impacted Japan and the Korean Peninsula in August 2019. Originating from a trough over the open Pacific Ocean on July 29, Francisco developed into a tropical depression on August 1. Tracking along a northwest course toward Japan, the system steadily intensified over the following days. It attained typhoon strength on August 5 and soon struck Kyushu at peak strength with winds of 130 km/h. Thereafter, the weakened storm traversed the Korea Strait before striking South Korea on August 6. Turning toward the east, Francisco transitioned into an extratropical cyclone on August 7. It later impacted Hokkaido before continuing across the northern Pacific and dissipating.
  In anticipation of Francisco impacting Japan, officials in Kyushu ordered evacuations for coastal residents in and around Miyazaki. Transportation across the region was disrupted, with flights and train service cancelled. The storm brought locally damaging winds and heavy rain. Wind gusts up to 143 km/h downed trees and power lines, leaving 24,710 households without power. Two people died and four others were injured in incidents related to the storm.
context_section_description: On July 29, 2019, the Joint Typhoon Warning Center (JTWC) 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. A defined low-level circulation developed the following day, with convective banding features organizing east of its center. Development was temporarily halted on July 31 by insufficient divergence over a majority of the system. Thereafter favorable conditions fostered organization. The Japan Meteorological Agency (JMA) classified the system as a tropical depression at 00:00 UTC on August 1. Similarly, the JTWC classified it as Tropical Depression 09W at 18:00 UTC.
  The JMA estimated the system to have become a tropical storm around 12:00 UTC on August 2. At this time, the agency assigned it the name Francisco. Traveling along a general northwest track toward Japan, the system steadily intensified and attained typhoon status around 09:00 UTC on August 5. Typhoon Francisco reached its peak intensity around 12:00 UTC with ten-minute sustained winds of 130 km/h (80 mph) and a pressure of 970 mbar (hPa; 28.64 inHg). The JTWC assessed the storm to have intensified slightly through 18:00 UTC, with maximum one-minute sustained winds of 140 km/h (85 mph). Maintaining this intensity, Francisco made landfall in Miyazaki, Kyushu, around 20:00 UTC (5:00 a.m. local time, August 6). 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.
  Tropical Storm Francisco made landfall in Busan, South Korea, at 11:20 UTC (8:20 p.m. local time) on August 6. Less than an hour after landfall, the Korea Meteorological Administration assessed Francisco to have degenerated into a remnant low; however, the JMA and JTWC continued monitoring it as a tropical cyclone. Emerging over the Sea of Japan early on August 7, the system weakened to a tropical depression. The JTWC estimated Francisco to have remained a tropical storm for 12 more hours before transitioning into an extratropical cyclone; however, the JMA maintained the system as a tropical cyclone until the following day as it turned east. The storm's remnants later impacted Hokkaido on August 8–9 before continuing across the open Pacific. The remnants of Francisco ultimately dissipated on August 11 well east of Japan.
