tormReady University

UAMS was one of the first universities in Arkansas to attain the StormReady University designation from the National Weather Service (NWS).

Issued when wind chill values will reach 0°F to -15°F, with average wind speeds around 10 mph or stronger. These conditions are expected to persist for 3 hours or longer.

Winter Weather Advisory

Issued when the following conditions are expected, separately or in combination:

Snow accumulations of 1 to 3 inches. An advisory may be issued for 1 inch or less if the time of year or special circumstances exist where extra caution is warranted by the forecaster (such as light snow falling on very cold roads and freezing on contact, causing significant travel hazards)
Sleet accumulations of less than 1/2 inch.
Freezing rain or freezing drizzle accumulations of less than 1/4 inch.

Flood Advisory

Snow accumulations of 4 or more inches in 12 hours or less or 6 inches or more in 24 hours or less. Forecasters may also issue this watch for lesser amounts, such as 2 to 4 inches, when snow could cause significant travel hazards or it is early in the season.
Freezing rain or freezing drizzle accumulations of 1/4 inch or more.

NWS Watches, Warnings & Advisories

Winter Storm Warning

Issued when hazardous winter weather is occurring, imminent or has a high probability of occurrence. Winter storm warnings are for the following conditions, separately or in combination:

Snow accumulations of 4 or more inches in 12 hours or less or 6 inches or more in 24 hours or less. Forecasters may also issue this watch for lesser amounts, such as 2 to 4 inches, when snow could cause significant travel hazards or it is early in the season.
Freezing rain or freezing drizzle accumulations of 1/4 inch or more.
Sleet accumulations of 1/2 inch or more.

Blizzard Warning

Issued for sustained wind or frequent gusts of 35 mph or stronger, accompanied by considerable falling and/or blowing snow, frequently reducing visibility to less than 1/4 mile—and when these conditions could last for three hours or longer.

Ice Storm Warning

Indicates that significant or possibly damaging accumulations of freezing rain and/or freezing drizzle are expected. This usually means accumulations of 1/4 inch or more of ice. Typically, these conditions involve plunging temperatures behind an arctic front sufficient to produce flash freezes, along with a significant reduction in visibility from falling and/or blowing snow.

Wind Chill Warning

Issued when wind chill values will reach -15°F or colder, with average wind speeds around 10 mph or stronger for one hour or longer.
