Please visit https://www.drought.gov/drought-status-updates/ for regional drought status updates. Tropical moisture resulted in unseasonably high precipitation amounts for early June, which is usually a dry month. This precipitation allowed for widespread downgrades from Extreme (D3) drought to Severe (D2) drought. However, long range precipitation totals are still below average for the water year. U.S. Drought Monitor Drought Intensity and Extent D4 (Exceptional Drought): None. D3 (Extreme Drought): Central Nye County, western Lincoln County, eastern Clark County, sections of Mohave County, and Death Valley in Inyo County. D2 (Severe Drought): Remaining areas of Lincoln, Clark, and Mohave counties, eastern San Bernardino, Inyo, and Esmeralda counties. D1 (Moderate Drought): Western San Bernardino County, sections of central Inyo County, central Esmeralda County. D0 (Abnormally Dry): The Eastern Sierra, Owens Valley, and White Mountains in Inyo County, far western Esmeralda County. Recent Change in Drought Intensity Four Week Drought Monitor Class Change. Drought Worsened: No widespread degradation was observed. No Change: Most of southern Nevada, southeastern California, and northwestern Arizona. Drought Improved: Northern Clark County, most of Lincoln and Mohave counties, sections of eastern San Bernardino County and Inyo County. Precipitation Remnant moisture from Tropical Storm Alvin resulted in unusually high precipitation amounts in early June, which is normally the dry season for the region. Some storms produced hail up to an inch in diameter on June 3 and 5. Temperature Maximum temperatures over the last 7 days have been near to slightly above normal in southeastern California and southern Nevada, and slightly below normal in northwestern Arizona. Maximum temperatures over the last 30 days have been near to slightly above normal across the area. Summary of Impacts Hydrologic Impacts Lake Mead is at 1,055.88 feet in elevation, or 31 percent full. Agricultural Impacts Rain was welcome for livestock, but planting schedules needed to be adjusted. Below average winter snowpack will impact rivers, streams and irrigation this summer. Fire Hazard Impacts Unseasonably high rain amounts could kick start the growth of fine fuels (grasses and invasive plants) that can dry out quickly, becoming fuel for fires. Other Impacts Bighorn sheep in the Muddy Mountains are being captured and relocated to northern Nevada and Utah due to a lack of food and water. Mitigation Actions Southern Nevada Water Authority switched to the summer landscape watering schedule. Hydrologic Conditions and Impacts Lake Mead is at 1,055.88 feet in elevation, or 31% full. Lake Mohave is at 644.19 feet in elevation, or 96% full. Lake Havasu is at 448.38 feet in elevation, or 95% full. The Bureau of Reclamation 24-month study indicates a decrease in Lake Mead’s elevation this summer. Lake Mohave and Lake Havasu remain steady. Agricultural Impacts Unseasonably high rain amounts were welcome for livestock. Planting schedules needed to be adjusted. Below average winter snowpack will impact rivers, streams and irrigation this summer. Groundwater and reservoirs may not be recharged with snowmelt. Fire Hazard Impacts Unseasonably high rain amounts could kick start the growth of fine fuels (grasses and invasive plants) that can dry out quickly, becoming fuel for fires. Fuels across southern Nevada and northwestern Arizona are approaching critical for most areas. Fuels are dry in southeastern California. Seven Day Precipitation Forecast No precipitation is expected for the next seven days.
