Official National Weather Service climatological reports for October 5, 2026, documented measurable rainfall across scattered southeastern U.S. sites, including 3.27 inches in Alma, Georgia, over 3 inches in Gainesville, Florida, and record daily totals near Charleston, South Carolina, where a slow-moving front and high moisture produced flash flooding. In contrast, most western, central, and northeastern stations recorded zero or trace amounts under drier high-pressure influence. Japanese Meteorological Agency data showed heavy accumulation in northern and western Honshu, such as 55 mm in Sapporo, while Vietnam’s cold-air outbreak triggered widespread showers from Hanoi southward. These verified observations from NWS, JMA, and regional networks determine market resolution based on location-specific precipitation thresholds, with any post-event data revisions or additional station reports serving as the final inputs.
