Take a look at what this blogger says about 40 to 45 mph winds:

"Cape May, NJ - Try taking a walk on the beach in 40 to 45 mile per hour winds.

"The weekend Noreaster that slammed the coast had the same barometric pressure as a low level hurricane. Maybe that's why I felt like Jim Cantore on the Weather Channel as I tried to cross Beach Ave. this morning. Maybe that's why there was no one else on the street."

45 mph is halfway between Beaufort Scale 8 & 9.

Here's a random sampling of Beaufort Scale 8 effects:

"When Beaufort scale 8 is reached, the local port authorities prohibit commercial vessels from leaving port."

"These advances [in the hovercraft] have been achieved by the introduction of twin propellers, a more powerful engine and a redesigned skirt system. The tapered skirt, which is deeper at the bow than the stern, cushions the effect of operating over larger waves and surface obstacles and enables the craft to operate in winds up to Beaufort Scale 8 and waves of up to 3.04 m."

All Signs Group: "When weather conditions reach 39 – 45 Beaufort scale 8 these conditions are no longer considered normal and we can accept no liability for any damage caused to or by our products."

"I have heard or read others, in their narrow mindedness, blaming Captain Roberts for the weather and current, as if sailing a vessel was as easy as driving a car. They should try it sometime, out there when mother nature unleashes her fury, even moderately (beaufort scale 8 = Gale Force, on a scale of 1 to 12. 12 being Hurricane) 39-46 miles per hour winds, the swells being 30 plus feet, as if it has to be that nasty to wreak havoc upon a ship. Talk about a grand time, you do the best you can to sail, and tho’ most of your canvas must be furled, you must leave at least one jib flying, which leaves you little to make your course and you find yourself at the mercy of all that is unholy, the brutality of an unforgiving wind and ever changing current. "

"The first recovery vessel to arrive on site was Ailette on December 13. However, at nightfall the wave height exceeded 6 m (Beaufort scale 8 to 9), making deployment of any equipment hazardous."

I once crossed the English Channel in a Force 9 gale. At times the ship dipped so much that the shore lights looked like they were in the sky. I'm not sure why the ferry was allowed to leave port but it made it safely back to England lighter of passengers stomach contents.

Wow! Amazing. In the sky--I can imagine that...how scary. Well, they just extended the wind warning to 7 p.m. tomorrow. Hm. The low pressure system looks like a giant fingerprint centered right on southern Michigan.

In other weather-related news, the Georgia drought caused stadium officials at last Saturday's U of G football game to command fans to not flush the stadium toilets, as past of a "Every Drop Counts" campaign.

When I lived in Boulder in the 80s, there would fairly regularly be wind gusts to 70mph+ and a few times it got over 100mph (http://www.cdc.noaa.gov/Boulder/wind.html). The high-profile vehicle warnings came pretty often as did the small dog warnings. (As in "better keep Toto inside or he will blow away.") It was scary but exhilarating.

JulieW: Wow! 70 & 100 mph! I absolutely love the notion of "small dog warning." That must be based on fact...I bet some tiny dogs did get whisked away by wind, poor things. I shouldn't laugh. It's not.....(schnork!)....not....(blerk!)....funny!--OK, it's funny.

Wow, this is neat: a current wind speed map. Great Plains being scoured right now.
