Early signs of drought concerns slip into Virginia
Parts of the Commonwealth are now considered "Abnormally Dry."
ROANOKE, Va. (WDBJ) - This week’s Drought Monitor confirms what we’ve all been thinking for the past month. It’s getting too dry.
The U.S. Drought Monitor, released July 16th, has now painted parts of northern Virginia as well as as western Virginia in what is considered to be D0 drought (Abnormally Dry). This is the first level of intensity and is a step below moderate drought.
One might imagine other areas in Virginia will be getting very close to the same designation if we don’t receive rain in the coming weeks. The report takes into account rainfall that has fallen up until the Tuesday before the report is released.
“The combination of heat and minimal rainfall was a concern for many agricultural areas as crops are at critical stages of growth and reproduction,” cites the drought report. With high evapotranspiration rates during the summer heat, topsoil moisture can become rapidly depleted and stress the crops.
HOW MUCH RAIN HAS FALLEN?
While June was quite the wet month for any areas, July has been quite the opposite. As of this article, the major climate reporting locations in Roanoke, Lynchburg and Blacksburg are 1-2″ below average for the month in terms of precipitation. In fact, as of July 15th, Roanoke hasn’t seen the first quarter inch of rain for the month. Looking back, no day had more than .15″ of rain since a storm dumped slightly more than an inch on June 19.
|LOCATION||RAINFALL THROUGH JULY 16||RANKING|
|ROANOKE||0.19″||3rd Driest Since 1912|
|LYNCHBURG||0.34″||10th Driest Since 1893|
|BLACKSBURG||0.70″||17th Driest Since 1893|
|BLUEFIELD||Trace||Driest since 1909|
Danville has received slightly more rainfall with several downpours so it’s not necessarily considered “dry.” However, the bulk of the region has been dry since the middle of June.

When it gets excessively hot and dry, your lawn’s and plant growth begin to slow, and in some cases, die out. Virginia Tech Cooperative Extension office offers a lawn offer a few tips in their article and podcast.
SIGNS OF DROUGHT STRESS
- Upward curling of leaves
- Yellowing and browning of leaves
- Under-sized fruit or leaves
- Blossom and fruit drop
- Needle drop on conifer and evergreens
WATERING TIPS DURING DROUGHT
- Trees and shrubs need at least 1 inch of water applied every week to 10 days to cope with lack of rain.
- Water slowly and deeply so water goes down into the soil
- Soaker hoses and drip irrigation are effective because they discharge even streams of slow, trickling water directly to the root zone.
- Water strategically. Plants absorb more water in the early morning, before the warming sun causes evaporation.
- Avoid using fertilizer during drought conditions. Fertilizer salts can cause root injury when soil moisture is limited.
No signs of a major pattern shift around in the immediate forecast. The heat and continue to be the big story with scattered to isolated storm chances. One could only hope for some rain from the tropics, but often that can take us on the other side too quickly.
