Delays Expected at Raliegh-Durham International (RDU) on February 21, 2019

Delays are expected at Raliegh-Durham International (RDU) today.

High Probability of Delays Between 8:00 AM on 2/21 and 8:00 AM on 2/21

During this time period the airport expects to experience mist which will cause a high likelihood that flights will experience delays.

Here is a look at what the forecast conditions are and what is required for normal operation:

Normal Forecast
Conditions None Mist, rain

Visibility Greater than 2 10
Wind Less than 11.8 MPH 7.1 MPH
Clouds Higher than 1,000 Overcast at 1,500

While the weather conditions should be good enough to land aircraft the low visibility caused by these weather conditions will probably require ATC to slow down the flow of traffic to ensure that aircraft arrive safely.

Medium Probability of Delays Between 8:00 AM on 2/21 AND 11:00 AM on 2/21

During this time period the airport expects to experience thunderstorms which will cause a medium likelihood that flights will experience delays.

Thunderstorms are potentially deadly for aircraft, mainly because of the unpredictable and severe winds that are associated with these storms. That wind causes a significant risk to landing aircraft and so airports will typically close during thunderstorms.

Lightning can also cause a hazard to ground staff, so airports may decide to stop servicing aircraft on the ground during these storms and for a period of time after they have passed.

Here is a look at what the forecast conditions are and what is required for normal operation:

Normal Forecast
Conditions None Thunderstorms, rain

Visibility Greater than 2 0.5
