|The Great Basin Weather and Climate Dashboard is a single stop for climate and weather information. It includes real time updates from the U.S. Drought Monitor, Western Regional Climate Center, National Weather Service and others.||http://gbdash.dri.edu/|
|The U.S. Drought Monitor is unique, blending numeric measures of drought and experts' best judgment into a single map every week. It started in 1999 as a federal, state, and academic partnership, growing out of a Western Governors' Association initiative to provide timely and understandable scientific information on water supply and drought for policymakers.||http://1.usa.gov/1mx7rHt|
|The U.S. Seasonal Drought Outlook depicts large-scale trends based on subjectively derived probabilities guided by short and long-range statsitical and dynamic forecasts. It is released quarterly.||http://drought.gov/drought/|
|The Palmer Drought Severity Index (PDSI)attempts to measure the duration and intensity of the long-term drought-inducing circulation patterns.||http://1.usa.gov/V8aTRJ|
| ||The U.S. Quarterly Drought Outlook is a two-page summary that looks at the likelihood of drought easing or intensifying; wildfire danger; drought disaster areas; the impact on hay, winter wheat and cattle in selected states; and chances for hotter than normal or wetter than normal conditions.||http://1.usa.gov/1skIx5t|
This web site provides BLM Nevada’s drought information and direction. It is intended for use by BLM personnel, public land users, and the public. While other topics will appear on this web site, the main subjects will be precipitation, expected plant growth, and livestock grazing management. BLM authorizes livestock grazing on most of the public lands in Nevada. Drought has two obvious impacts on public land grazing, reduced forage production and reduced amount and availability of drinking water. Both situations have repercussions beyond range management. Sometimes livestock management has to be modified in response to drought, and sometimes it can be used to manage drought impacts.
In the Great Basin precipitation occurs November through May that determines the amount of vegetation produced in the next growing season. The Natural Resources Conservation Service’s (NRCS) snow surveys are read monthly from January through April (www.wcc.nrcs.usda.gov/wsf/wsf.html). This is one of the better predictors of water availability in Nevada. By May most grazing management decisions have been made.
