Lala Approaching Hawaii; Flash Flooding Risks; Excessive Heat

Lala, may become a hurricane, is expected to impact Hawaii this weekend. Heavy rainfall, strong winds, dangerous surf and localized flooding are expected. Heavy rainfall and flash flooding concerns from the mid-Mississippi Valley, Ohio Valley into the central Appalachians continues, with the threat shifting toward the mid-Atlantic later this weekend. Record heat continues for areas of the South. Read More >

Overview

Record-setting rainfall of 6-12 inches (and more in a few areas) along the headwaters of the Kickapoo River near and north of Ontario, Wisconsin produced a major flood down the entire span of the river between August 28th and 30th, 2018. In most areas, this flood exceeded the previous record flood of June 9-10th, 2008, with new flood crest records being established in many areas. Please note that as of September 7th, 2018, we are still awaiting final flood crests from the United States Geological Survey for Ontario and La Farge, Wisconsin as those river gauges failed during the flood. Also, this information should be considered preliminary and could change if new data are received regarding the highest river levels.
