Seattle Tacoma International (SEA) flights delayed Feb 9, 2019

Flights to and from Seattle Tacoma International (SEA) are being delayed for approximately 4 hours and 33 minutes because weather conditions at the airport are too dangerous to safely land flights on the normal schedule.

This post is updated every 15 minutes. All times are listed in local time for the airport.

Will my flight be impacted?

Probability your flight will be impacted based on how far in the future it is scheduled to leave:

60 Minutes Three Hours Six Hours
HIGH HIGH HIGH

The airport is currently experiencing delays due to the presence of snow and ice on the runways and airport surface. These conditions are not expected to improve quickly and will likely continue throughout the day.

It is very likely that your flight may be delayed or canceled even after the snow has stopped.

Why Is This Happening?

Here are the current weather conditions at Seattle Tacoma International and an overview of what is required for “normal” operations:

Normal Current
Conditions Clear Light snow fog
Visibility Greater than 2 0.5
Wind Less than 11.8 MPH 14.1 MPH
Clouds Higher than 1,000 Overcast at 0

Visibility is currently 0.5 statute miles, which is less than the normal 2 statute miles needed for aircraft to safely see each other and the runway during landing. The clouds are currently 0 feet off the ground, while flights typically need at least 1,000 feet to safely land on the normal schedule.

The current snow is forecast to end by 2:00 AM on 2/9.

Snow and ice are pretty much the worst case scenario for airplanes. The snow reduces visibility making it difficult to land, and ice on the runways can make it difficult for airplanes to slow down and stop. In these situations air traffic control will reduce the number of airplanes taking off and landing to give flights more time to safely clear the runway and move between the runway and the terminal. Even after the snow has stopped and the weather has started to improve it may take a significant amount of time to clean the ice and snow from the runway.

Here’s what the current aviation forecast says will happen over the next few hours for the cloud cover:

Change From To Time
Raise 0 3,000 2:00 AM on 2/9
Raise 3,000 5,000 6:00 AM on 2/9

Here’s what the current aviation forecast says will happen over the next few hours for the visibility:

This situation is the most likely to see flights canceled, and flights are nearly guaranteed to be delayed.

Probability your flight will be impacted based on how far in the future it is scheduled to leave:

MEDIUM LOW LOW

Since this is a temporary situation it is expected that the delay will not continue for very long. As such while your flight may see a minor delay it is not likely to be canceled unless there are other issues for that specific flight.

Why Is This Happening?

Airports sometimes experience situations where more aircraft are trying to take off and land than the air traffic controllers can safely handle. During these periods the air traffic controllers can slow down the rate at which new aircraft are allowed into the area. This process is called “metering,” and will end when the local air traffic controllers can safely handle normal operations again. As such there is no way to definitely say when the delays will end.

Predicting exactly when thunderstorms are scheduled to impact an airport is very difficult, so airlines may dispatch flights in the hopes that the weather will improve by the time the flight arrives. More common is that flights will be delayed until the thunderstorm has passed.

Why Is This Happening?

Here are the current weather conditions at Las Vegas McCarran International and an overview of what is required for “normal” operations:

The airport is currently experiencing delays because there are thunderstorms in the area. Thunderstorms are extremely dangerous to aircraft, with wildly shifting wind currents and severe turbulence. This can cause aircraft to crash on takeoff and landing, and even cause damage to aircraft on the ground. Thunderstorms usually roll into the area quickly and then leave just as fast, but the delays they cause can have knock-on impacts throughout the day.
