Friday update – Isaac and W. Michigan Weather

August 30th, 2012 at 5:49 am by under Bill's Blog, Weather

  As you can see some very significant flooding going on in LA and MS.  (click the pics. to enlarge).  Up to 20″ of rain has already fallen.  So far, 2 fatalities.  There were also 2 injuries with an Isaac-related tornado at Crandall, Mississippi.   With the storm not moving much, you can see the “training” of heavy rain as the bands set up over the same area.  One levee has been topped, but most levees and the N.Orleans pumps are still holding fine.  Nearly 2,000 people have been rescued – many of those were in mandatory evacuation areas, but refused to leave (very frustrating).  The Louisiana state and city government seemed to be more ready for this hurricane than Katrina and as I write this.  14 Billion was spent on levee repair.  93% of Gulf oil production has been shut down by Isaac.  Isaac is now a Tropical Depression.  It’s drifting slowly northward and it’s slow movement will continue to bring heavy rains (see links in thread below).  The National Guard has been called out in SE Louisiana, where at least 12 have been arrested for looting.  Approximately 700,000 customers have been without power.  That includes nearly half of the state of Louisiana and another 150,000 in Mississippi.   There were a handful of relatively small tornadoes spun off by the storm in S. Mississippi and S. Alabama.   Isaac also left heavy rain (up to 10″) in Florida.

Here in Michigan, we stay dry…upper 80s to low 90s tomorrow.  What’s left of Isaac could still produces a few showers/isolated t-showers in extreme S. Michigan (south of I-94), but don’t hold your breath.  It looks like the rain will pretty much stay down in Illinois and Indiana.  The NAM (Caribou) model is dry Saturday for G.R. and Kalamazoo.   The European has us dry over the weekend with a weak front stalling out and giving us a chance of a thundershowers on Monday.  It only gives G.R. 0.01″.   There’s an Air Quality Alert for the lakeshore counties and Kent Co. for Friday, though it’s iffy whether we can reach the Air Quality Threshold with a west wind.

Gayle and I went to Gun Lake to kayak Weds. and the wind was calm much of the time we were there…nice day, we had a picnic – watched several deer come back through the water from an island east of the State Park peninsula and saw the full moon come up in the east.  At Lake Michigan there’s a moderate chance of pier/breakwater currents.  Grand Rapids is 0.3 degree cooler than average so far this month and we’re starting with a low at least down at 57 this Thurs. AM (average high/low is 79/59), so despite two warm days, we may not be able to make that up.  Sept. 2011 was the last month that was cooler than average in G.R.  The average wind speed in G.R. this month has been only 6.3 mph.  The average wind speed for Weds. was 3.1 mph and we had 100% sunshine.  We’ve now had 9 days with an average wind of less than 4 mph.  Here’s more coverage of Isaac from WWLTV, WGNO, WSDU, and NOLATropical Storm Leslie will be named soon – it should become a hurricane but stay east of the U.S.

    What did they receive there, something like over 2 feet of rain? WOW! They cannot take all the rain with the surge. Also, that tropical storm is moving so very slow, that just escalates the rain totals. I thought the engineers were going to try to release some of water from one of the levees to help with surge?
    Looks like cloud cover and perhaps a sprinkle for us from TS Isaac?

    I am curious to know if any past hurricane has been fast/ strong enough to have any significant impact on MI …Bill?

    1. Brad says:

      That’s a good question- I know we have had a few that brought a few inches of rain from time to time, and some gusty winds, but I doubt any have been damaging. Ah, here’s a pretty cool link! http://www.crh.noaa.gov/dtx/stories/dtxcane.php

        Interesting… Thanks Brad!

      There was a hurricane in (I believe) 1986 that produced 5″ of rain at one station in Van Buren County. It was a flare-up of thunderstorms at night in the center of the circulation.

  3. Jordan (Twin Lake) says:

    Models show area in IL and IN receiving 12+ inches from the remains of Issac that’s a lot but much needed in those area that will swipe the drought right of the am in those areas!

    *map*stupid auto correction it doesn’t even know map!!!

      One heavy rain doesn’t mean that the drought will be gone. That’s like Bill posting that a cool summer is proof that global warming is fabricated. ;) Of course, we haven’t heard much of that talk this summer have we?

        Check out the southern hemisphere weather during our summer this year Kev. Chilly!

      2. Bill Steffen says:

        Global temperature is right at average for 2012 so far: http://policlimate.com/climate/ncep_cfsr_t2m_ytd_anom.png Very warm over much of the Arctic and to a slightly lesser extent over Central North America, but cool over much of the globe.

    I know this doesnt have much to do with this discussion but guess what? Gas is down to 3.92!!! Never thought I would be excited about it being so high

    1. Brad (Lawrence) says:

      Still 4.08 here. ‘Sigh’

  6. bnoppe(Albion) says:

    Latest forecast calls for most of Isaacs moister to remain to our south

  7. Dan says:

    We may not even receive clouds from Isaac. Interesting to see how this system is moving. Seems to take forever, at the shoreline. Gives a good indication of the blocking highs and how the jet stream is moving things along!

    Is there any chance of the remnants of Isaac making it back out to the open waters and re-forming?
