During the last 36 hours, KIAD used runway 30 almost exclusively for departures and arrivals due to strong, gusty NW wind. Shifted back to the north runways about noon today. Stuffing all of the afternoon international arrivals onto a single runway made for some interesting traffic management. KIAD is eventually supposed to get a second crosswind runway.
The runway 30 visual option pops up about 4 or 5 times per year due to strong NW wind but the duration is usually less than 8 hours. The last couple of days were truly unusual for KIAD.
