Fri, 09 Oct 2026 11:00:00 -0400 global https://www.ncei.noaa.gov/access/monitoring/monthly-report/tropical-cyclones/202609 https://www.ncei.noaa.gov/access/monitoring/monthly-report/tropical-cyclones/202609 Nineteen named storms occurred across the globe in September, which was above the 1991-2020 average of 16.3. Nine of those reached tropical cyclone strength (greater than or equal to 74 mph), and six reached major tropical cyclone strength (greater than or equal to 111 mph). The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was 206.4x10^4kt^2 or about 130% of the 1991-2020 average for September.

Global Sea Ice Extent was 22.13 million square km (8.54 million square miles), 8.54% below the 1991-2020 average.

European Centre for Medium-Range Weather Forecast (ECMWF) ERA5 Reanalysis: Global precipitation data (1940-2026), as well as temperature data for Australia. Thu, 10 Sep 2026 11:00:00 -0400 national https://www.ncei.noaa.gov/access/monitoring/monthly-report/tornadoes/202608 https://www.ncei.noaa.gov/access/monitoring/monthly-report/tornadoes/202608 The most favorable region for tornadic development during August is along the northern tier states, where the late summer jet stream is typically positioned. Gulf and Atlantic Coast states also experience an elevated incidence of tornadoes during August due to tropical cyclone activity. According to data from NOAA's Storm Prediction Center (SPC), there were 98 preliminary tornado reports during August, representing approximately 121% of the 1991-2020 August average of 81 tornadoes.
