![]() ![]() The statewide damage was estimated to be $126 million, around $850 million today adjusted for inflation, the Richmond Times-Dispatch reports.Agnes killed more than 100 people in the U.S., including 13 Virginians. #James river water level full#This storm tracker contains data from 1851.Fifty years ago this week, the remnants of Hurricane Agnes hit the city in full force, bringing 7 inches of rain in six days - and causing the worst flood in Richmond's modern history.ĭriving the news: Agnes remains one of the largest June hurricanes on record, and the subsequent widespread flooding made it the most destructive hurricane in U.S. Storm Tracker and Model MixerĪ hurricane watcher's guide to the latest track and model forecasts. The Air Quality Index (AQI) translates air quality data into numbers and colors that help people understand when to take action to protect their health.

Weather Prediction Center forecasts the probability that rainfall will exceed flash flood guidance within 25 miles of a point. ![]() For more recent tornadoes, clicking deeper provides more details, damage estimates and whether someone was injured or killed in the storm. This interactive map, which contains data from January 1950, pinpoints where a cyclone touched down and traces its path of destruction. A history of twisters: Tornadoes in Florida since 1950s Common reasons for a “Not ranked” category are ice-affected flows and gages that only record the stage (elevation) of the flow.Īs storms strike, this interactive map is your guide to impacts and damage reports coming into National Weather Service stations nationwide. The flow category “Not ranked” indicates that a flow category has not been computed. Similarly, the flow category “High” indicates that the estimated streamflow is the highest value ever measured for the day of the year. The flow category “Low” indicates that the estimated streamflow is the lowest value ever measured for the day of the year. For example, a discharge at the 75th percentile is the same as a discharge at the 25th percent exceedance (100-75=25). It is simply obtained by subtracting the percentile scale value from 100 percent. In some hydrological studies, particularly those related to floods, a variation of the percentile known as the "percent exceedance" is used. a percentile less than 25 is considered below normal.a percentile between 25 and 75 is considered normal.a percentile greater than 75 is considered above normal.For example, on the map of daily streamflow conditions a river discharge at the 90th percentile is equal to or greater than 90 percent of the discharge values recorded on this day of the year during all years that measurements have been made. ![]() A percentile is a value on a scale of one hundred that indicates the percent of a distribution that is equal to or below it. ![]()
