If the Storm Prediction Center (SPC) issues a 45% probability of severe wind for any specific location, it means that there is a 45% chance of a wind gust of at least 58 mph within 25 miles of that location. This may seem like a low number, but relative to a typical day it is quite high.

If there is an 80 percent chance of rain and a 30 percent chance of wind and rain what is the probability that it is windy given that it is rainy Round your answer to the nearest percent.?

To get the answer to this question you need to work out what 30% of 80% is. To do this you need to divide 30, by 80, then multiply your answer by 100. 30/80=0.375, 0.375*100=37.5, 37.5 to the nearest percent is 38%

What would happen if there was ever an 60 percent wind threat area an 15 percent hail threat area and an 5 percent tornado threat area from the SPC for Western NC one day?

It is difficult to say exactly what would happen, as a severe weather outlook outlook is based on a forecast weather event which may or may not develop as expected. Such an outlook, however, would suggest an event in which there was a high risk for severe and a slight risk for hail and tornadoes. Such and outlook might suggest the possible development of a squall line, perhaps with bowing segments. Such an event could potentially produce widespread straight-line wind damage accompanied by a few tornadoes and some severe hail.
