A University of Washington weather expert says that wind forecasts were known a day ahead of the tragic crane collapse in Seattle on Saturday.

鈥淎n important issue is the forecastablity of this,鈥� UW Climatologist told 成人X站 Radio. 鈥淎nd the forecasts were out for 20-30 mph winds for that period. So the forecasts a day before were quite good at predicting the strengthening of the winds on Saturday.鈥�

The exact cause of the crane collapse in Seattle’s South Lake Union neighborhood Saturday is under investigation.

In a recent blog post titled ” Mass explains that the winds were fairly strong that afternoon, according to measuring devices around Lake Union. The closest device to the scene was an anemometer (which measures wind speed) near the Center for Wooden Boats. Gusts around 25-35 mph were recorded around 3:30 p.m., Mass says. That’s 10-15 mph stronger than originally thought.

鈥淭hey had an anemometer which measured 35 mph gusts,” Mass said. “The winds might have been revved up a bit because the winds had to pass over the building. But I think 25-35 mph is pretty consistent with that observation. There was a 25 mph wind further up the lake, not too far from Gasworks Park, so a number of locations reported this surge of northerly winds that pushed down from the north into the Seattle area.鈥�

One thing Mass notes is that a “” was not a factor in Saturday’s incident, as some have speculated. A microburst is a very localized downdraft of air, usually within a storm.

Instead, a few conditions came together to send winds into South Lake Union. Wind factors can vary from location-to-location, especially depending on the terrain or how rough the surface is. This location is down from Lake Union, which is fairly smooth.

鈥淚t was kind of a bad location if you don鈥檛 like strong northerly winds,鈥� he said. 鈥淲ater is aerodynamically smooth, so you don鈥檛 have all the drag from trees and buildings and stuff like that. So winds can get stronger over the water than they are over land.鈥�
