The August 21-22, 24-hour total of 9.19 inches tied for the second highest 24-hour total. According to National Weather Service records, prior to this week’s event, the Dallas-Fort Worth Area went 67 days without measurable precipitation, the second longest streak on record going back to 1898. A few impressive statistics include the following. Analysis will continue next week as more data become available. EDT), data communications issues caused by the flooding, and lags in the hydrologic system in response to rainfall events means that the full impact of this storm on drought conditions is not yet apparent. Rainfall close to the data cut off time (Tuesday at 8:00 a.m. All states in the region show improvements. This week’s storm event led to broad 1 and 2-category improvements across large parts of the South. The state drought team notes below normal levels in Lake Kissimee and inflows into Lake Okeechobee in addition to dry soils and stressed vegetation. Abnormally dryness (D0) and moderate drought (D1) expanded in the Florida Peninsula where rainfall deficits continue to build. Rainfall of 150 to 300 percent of normal for the week erased short term moisture deficits, replenished soils, and restored streamflows. Spotty, heavy rain fell across the Southeast this week leading to improvements to areas of moderate drought (D1) and abnormal dryness (D0) in the Carolinas. Recent rains improved abnormally dry conditions (D0) in northern Maine, northern New Hampshire, and Delaware. Likewise, drought expanded in Connecticut (moderate drought, D2) and New Jersey (moderate and extreme drought, D1 and D2) where deficits are equally impressive. Vermont saw increases to moderate drought (D1) areas where rainfall deficits of near 6 inches over the last 90 days dried out soils and lowered streamflows. ![]() Northeastĭrought persisted or expanded across much of the Northeast. The Midwest, Southeast, and Northeast saw a mix of improvements and degradations. Drought expanded in the Northwest was warm, dry conditions continued across the region. The magnitude of this event meant prioritizing improvements on this week’s map in these areas and in the Southwest, where the Monsoon season remains active. The heavy rainfall and flooding led to communications outages at the National Weather Service office leaving climatologists without access to important data and tools needed to fully analyze the effect of this event. Record-breaking rainfall led to aggressive improvements in drought conditions across parts of the South.
