Weather
A METAR (weather observation) for Pearson was released almost exactly at the time of the accident. It stated that the weather at 20:04 UTC (16:04 EDT) consisted of winds from 340° true (north-northwest) at 24 kn (44 km/h) gusting to 33 kn (61 km/h), with 11⁄4 miles (2.0 km) visibility in heavy thunderstorms and rain. The ceiling was overcast at 4,500 feet (1,400 m) above ground level with towering cumulus clouds. The temperature was 23 °C (73 °F). According to the Canada Air Pilot, runway 24L has a heading of 227° true (237° magnetic), and the minima for the ILS approach are ceiling 200 feet (61 m) above ground level and visibility 1⁄2 miles (0.80 km) or runway visual range (RVR) of 2600. The METAR for 21:00 UTC (17:00 EDT), nearly an hour after the accident, shows wind backing to the south and improving conditions generally, but includes "FU ALF" in its remarks to indicate smoke aloft from the burning plane.
The Canadian Broadcasting Corporation reported that the crash occurred two hours after a ground stop was declared at the airport because of severe thunderstorms in the area ("red alert" status, which, for safety reasons, halts all ground activity on the apron and gate area. Aircraft can still land, and take off if still in queue). Visibility at the time of the accident was reported to be very poor. There was lightning, strong gusty winds, and hail at the time and the rain just began as the plane was landing. Within two hours the winds increased from 5 to 30 km/h (3 to 20 mph) and the temperature dropped from 30 to 23 °C (86 to 73 °F). A severe thunderstorm warning was in effect since 11:30 a.m. and all outbound flights and ground servicing operations had been canceled but landings were still permitted.

Famous quotes containing the word weather:
“Is it possible
That any may find
Within one heart so diverse mind,
To change or turn as weather and wind?
Is it possible?”
—Sir Thomas Wyatt (1503?–1542)
“The mark of the man of the world is absence of pretension. He does not make a speech; he takes a low business-tone, avoids all brag, is nobody, dresses plainly, promises not at all, performs much, speaks in monosyllables, hugs his fact. He calls his employment by its lowest name, and so takes from evil tongues their sharpest weapon. His conversation clings to the weather and the news, yet he allows himself to be surprised into thought, and the unlocking of his learning and philosophy.”
—Ralph Waldo Emerson (1803–1882)
“Winter lies too long in country towns; hangs on until it is stale and shabby, old and sullen. On the farm the weather was the great fact, and men’s affairs went on underneath it, as the streams creep under the ice. But in Black Hawk the scene of human life was spread out shrunken and pinched, frozen down to the bare stalk.”
—Willa Cather (1873–1947)
