SYNOPSIS... As of January 16th 2018, the U.S. Drought Monitor indicates that drought conditions have remained steady since the beginning of the year. D1 (Moderate Drought) conditions are still designated for almost all of northern and central Virginia, with the exception of Highland, Page, Shenandoah, Frederick, and Clarke Counties. D1 (Moderate Drought) conditions are still designated in the District of Columbia and most of the Baltimore and Washington metropolitan areas in Maryland. A very small area west of this is designated as D0 (Abnormally Dry), including the rest of Northern Virginia, the extreme eastern West Virginia Panhandle, and the Catoctin Mountain Region of Maryland. SUMMARY OF IMPACTS... State and Local Declarations: A Drought Watch has been declared by the Virginia Department of Environmental Quality (DEQ) for all of northern Virginia, except for King George County, Highland County, and communities whose water supplies come from the Potomac River or Occoquan Reservoir. No other state or local declarations are known as of the time of this statement. Hydrologic Impacts: Recent rains improved soil moisture back to normal in northern Maryland. However, the rest of the Moderate Drought area remains below normal, and is lowest along the Potomac River from DC southward -- below the 5th percentile. The recent rains finally stopped the slide in groundwater levels. They`re still below normal virtually areawide, but at least they appear to have bottomed out for the season. Typically this happens in September or October; this year it did not happen until January. As of late December, the towns of Front Royal and Strasburg had implemented voluntary water restrictions due to low streamflows in the South Fork Shenandoah River and North Fork Shenandoah River, respectively. At the time of this statement, these voluntary restrictions were still in place. Some municipalities implement voluntary or mandatory water restrictions when streamflow levels drop. Please check to see if your community is included in these water restrictions. CLIMATE SUMMARY... Recent rains have helped lessen deficits a bit, especially in north central Maryland. In the last 30 days, amounts have been between one and three inches liquid equivalent. This is just slightly below normal in north central Maryland, but is less than half of normal in much of the rest of the Moderate Drought area. The 60 day deficits in the Moderate Drought area are still 2 to 6 inches, with 90 day deficits of 2 to 8 inches. There is an area along the Blue Ridge and in the Charlottesville area that has even longer-term rainfall deficits, and this area could be close to further degradation of drought status in the coming weeks. PRECIPITATION/TEMPERATURE OUTLOOK... Unfortunately, not much relief is in sight. There is a chance of rain next Monday night and Tuesday (January 22nd/23rd), but expected amounts are just 1/4 to 1/2 of an inch. The outlook for Week Two (January 25-31) hints at just one shot of rain during that week as well. Temperatures for the two week period are expected to average above normal, though there will be at least one chilly period between now and the end of the month. The experimental Weeks 3 and 4 outlook through February 9th favors continued above normal temperatures but favors above normal precipitation from DC north and west. The Drought Outlook indicates little change in drought conditions is expected through the end of April. HYDROLOGIC SUMMARY AND OUTLOOK... Streamflows remain below normal to much below normal, and some streams as of January 18th are still being affected by ice. Streamflows will be variable in the coming two week period but will likely continue to average below normal. NEXT ISSUANCE DATE... The next scheduled issuance of the Drought Statement will be Thursday, February 1st, 2018. A supplemental update will be issued on Thursday, January 25th, if conditions change enough to warrant an update. && RELATED WEB SITES...
