View in Map RoomThis layer displays areas that experienced dry or drought conditions in the last seven days. Data are retrieved as shapefiles from the U.S. Drought Monitor and are updated on a weekly basis. The affected areas are represented by polygons, which are classified according to drought intensity. Using quantitative and objective indicators, as well as local condition and impact reports, the U.S. Drought Monitor defines each drought intensity level as follows:
D0 – Abnormally Dry
D1 – Moderate Drought
D2 – Severe Drought
D3 – Extreme Drought
D4 – Exceptional Drought.
For more information about the data, please see the U.S. Drought Monitor Data Classification web page.
View in Map RoomLayer displays the percentage of weather observations in 2011 with high heat index values (103F or higher) by county.
View in Map RoomThis layer depicts average annual precipitation amounts based on data from 1981 to 2010. Data was obtained from the PRISM Climate Group at Oregon State University. PRISM models climate information using a process which incorporates a digital elevation model. Monthly average data is also available.
