A flood watch is in effect for portions of Virginia, including Augusta County. National Weather Service has issued a time sensitive severe alert. A flood watch is in effect Tuesday from 5 p.m. to ...
While most areas from central Texas to Kentucky are projected to pick up rainfall totals from 1 to 2 inches from this event, there can be higher totals ranging from 2 to 4 inches along a corridor ...
Some areas in Kentucky received more than 6 inches of rain within a 48-hour period, resulting in "widespread flooding issues," according to the National Weather Service in Louisville.
Most modern rain gauges generally measure the precipitation in millimetres in height collected during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch. [16] Rain gauge amounts are read either manually or by automatic weather station ...
Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as a weather radar. When classified according to the rate of precipitation, rain can be divided into categories. Light rain describes rainfall which falls at a rate of between a trace and 2.5 millimetres (0.098 in) per hour. Moderate rain describes ...
Pan evaporation is a measurement that combines or integrates the effects of several climate elements: temperature, humidity, rain fall, drought dispersion, solar radiation, and wind. Evaporation is greatest on hot, windy, dry, sunny days; and is greatly reduced when clouds block the sun and when air is cool, calm, and humid. [ 1 ]
Rainfall totals of 0.25-0.50 of an inch are expected in and around the Los Angeles area through Friday morning, with closer to an inch of rain possible for Santa Barbara.
The scale of dBZ values can be seen along the bottom of the image. dBZ is a logarithmic dimensionless technical unit used in radar.It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).
