Monday & Tuesday: Hurricane Sandy To Break Bad On Lakefront.

From Uptown Update

Hard to believe, but there's a chance Hurricane Sandy could even affect us in Uptown:

The larger concern is northerly winds of around 60 miles per hour expected to churn Lake Michigan waters starting Monday and continuing for around 48 hours. The weather service said winds probably will reach gale- or storm-force and that by Tuesday night, some waves could be 33 feet.

What happens will depend on where Sandy makes landfall and how it interacts with other systems, Seeley said.

Mariners without the proper experience or equipment should stay on land, forecasters said. The waves will batter beaches and are expected to cause shoreline erosion.

Flooding could occur on Lake Shore Drive and on the lakefront bicycle and pedestrian path.

Any mariner with half a brain will stay off the lake regardless of experience or equipment.  This is forecast to be as bad as or worse than the storms that broke boats loose from their moorings in Monroe Harbor last year.  And, cyclists, don't forget the folks who were almost washed into the lake at Oak Street.

Not exactly sure which site Gene got his info from, but this is the National Weather Service warning:

As it says at the beginning of my post, Uptown Update, a local blog for my area of the city. Just listen to the weather forecast on your favorite TV station tonight. The worst of it seems to be Tuesday.

I'm thinking about risking the LFP this morning at least, then I'll probably ride through the city until Thursday or so.

Well, my feet got wet, but I managed to keep myself from being washed away into Lake Michigan.


Seriously, I'd stay away from the LFP until this thing passes. It will get much worse, before it gets better.

I snuck in on the LFP as well this morning, avoided the majority of any wash.  Not going to push my luck tonite though.

I rode through the streets this morning and had no problem – not even windy. I read that the winds aren't supposed to get bad until late tonight and last until late Tuesday night. I'm debating if I was going to ride tomorrow, wondering if streets will be okay or not.

I figured there would be no flooding inland; I was more concerned about riding a bike in 60 MPH winds.

Inland the only problems you'll have will be the wind. The streets will be fine.

Winds inland will not be 60 mph.  Forecast is for mid 20s mph, however, and there could be gusting over 30 mph.  Those kind of gusts practically stop me in my tracks, but my ride is only 4 miles on side streets so I think I am going to try it.

Actually, marine forecast is *only* 45 mph on the lake.

Rrrrr, shiver me timbers, but it sure be nice to have a sailor who knows the ropes among us land lubbers.

So I was not quite right about the expected winds!  Our building management just sent a memo out notifying us of the following National Weather Service Wind Advisory:

 WIND ADVISORY IN EFFECT FROM 1 AM TO 7 PM CDT TUESDAY... 

THE NATIONAL WEATHER SERVICE IN CHICAGO HAS ISSUED A WIND ADVISORY... WHICH IS IN EFFECT FROM 1 AM TO 7 PM CDT TUESDAY. THE HIGH WIND WATCH IS NO LONGER IN EFFECT.

* TIMING... LATE TONIGHT THROUGH EARLY TUESDAY EVENING.

* WINDS... NORTHERLY AT SUSTAINED SPEEDS OF 30 TO 35 MPH WITH GUSTS OF 45 TO 55 MPH. THE STRONGEST WINDS WILL BE NEAR THE LAKE MICHIGAN SHORE.

* IMPACTS... THE STRONG WINDS COULD RESULT IN MINOR WIND DAMAGE... INCLUDING DOWNED TREE LIMBS AND POWER LINES. HIGH RISE BUILDINGS NEAR THE LAKE INCLUDING TALLER BUILDINGS IN DOWNTOWN CHICAGO WILL EXPERIENCE EVEN STRONGER WINDS... POTENTIALLY WITH OCCASIONAL GUSTS TO NEAR 60 MPH... JUST A COUPLE HUNDRED FEET ABOVE THE GROUND. BE CERTAIN EVERYTHING THAT COULD BE SUSCEPTIBLE TO HIGH WINDS IS SECURED. THE STRONG NORTHERLY WINDS MAY ADVERSELY IMPACT HIGH PROFILE VEHICLES... ESPECIALLY ON EAST TO WEST HIGHWAYS.

PRECAUTIONARY/PREPAREDNESS ACTIONS... 

A WIND ADVISORY MEANS THAT SUSTAINED WINDS OF 30 TO 39 MPH... OR GUSTS BETWEEN 45 AND 57 MPH... ARE LIKELY. WINDS THIS STRONG CAN CAUSE MINOR PROPERTY DAMAGE UNLESS PRECAUTIONS ARE TAKEN. DRIVING MAY BE DIFFICULT... ESPECIALLY IN HIGH PROFILE VEHICLES. MOTORISTS SHOULD BE ALERT AND USE CAUTION.
