Runoff from the moderate to heavy rainfall will likely cause flooding. The heaviest rainfall and greatest risk for flash flooding is expected along the Blue Ridge Escarpment and the southern and eastern-facing slopes of the mountains in western North Carolina. Rainfall totals on 3-5 inches with isolated amounts between 6 and 8 inches are possible in these areas. This will not be anywhere near the magnitude of flooding that occurred during Helene. - http://www.weather.gov/safety/flood
INSTRUCTION: A Flood Watch for flash flooding means there is a potential for rapid onset flooding based on current forecasts. Flash flooding is a very dangerous situation and may impact areas that do not typically flood. Please monitor the latest forecasts and be prepared to take action quickly should Flash Flood Warnings be issued. Rainfall of more than five inches in similar storms has been associated with an increased risk of landslides and rockslides. If you live on a mountainside or in a cove at the base of a mountain, especially near a stream, be ready to leave in advance of the storm or as quickly as possible should rising water, moving earth, or rocks threaten. Consider postponing travel along mountain roads during periods of heavy rainfall.

Altostratus clouds form at mid to high-level altitudes
(between 2 and 7 km) and are created by a warm, stable air mass which causes
water vapor
to condense as it rise through the atmosphere. Usually altostratus clouds are
featureless sheets characterized by a uniform color.
In some cases, wind punching through the cloud formation may give it a waved
appearance, called altostratus undulatus. Altostratus clouds
are commonly seen with other cloud formations accompanying them.

Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.
