Heavy snow, rain, and flooding for the Northeast U.S.
The winter of 2009-2010 continues its relentless onslaught over the U.S. today, as a powerful low pressure system intensifying along the East Coast brings heavy snow, flooding rains, and high winds to New England and the Mid-Atlantic. The storm has already dropped more than two feet of snow over Eastern New York near Albany, and surrounding regions of Western Massachusetts and Southern Vermont. These regions are now seeing rain mixed in with the snow, which will limit further accumulations to 1 - 3 inches. Farther east, flooding is a concern for most of Connecticut, Massachusetts, Rhode Island, southern New Hampshire, and portions of western Maine, where heavy rainfall of 1 - 3 inches on top of a snow pack with a high water content has created runoff that has already swollen many rivers to flood stage. Heavy snow is the main concern over southeast New York, northern New Jersey, and northeast Pennsylvania. The unusually slow-moving storm is expected to drop snow amounts of up to 18" in the Pocono Mountains of northeast Pennsylvania, and in northern New Jersey. New York City, whose 30.5" of snow so far this winter is 13" above average for this date, could get up to a foot of wet, heavy snow. Philadelphia's 73" of snow for the season will get an 8 - 12" boost from the storm, taking their record snowiest winter even further into record territory. Wind gusts of 30 - 40 mph in combination with the very wet, heavy snow will make power outages a problem over much of the region.

Update on this Saturday's major winter storm in Europe
Computer forecast models continue to forecast the development of a powerful winter storm that will rapidly intensify Saturday morning into a meteorological "bomb" that will bring high winds and flooding rains to Portugal, northern Spain, and possibly France. However, today's model runs are less aggressive in deepening the storm, and no longer call for the storm to be as intense as last year's Winter Storm Klaus. Klaus, which hit northern Spain and southwest France January 23 - 25, was Earth's most costly natural disaster of 2009, causing $5.1 billion in damage and killing 26. Klaus peaked in intensity at 967 mb, and brought wind gusts of 120 mph (193 km/hr) to Formiguères, France, 125 mph (200 km/hr) to Portbou, Spain, and 134 mph (216 km/hr) to Port d'Envalira, Andorra. Last night's 00Z (7pm EST) run of the ECMWF model and GFS model called for Saturday's storm to have 974 - 976 mb central pressure. Saturday's storm still has the potential to be plenty damaging, as winds of tropical storm force with gusts to hurricane force should affect a large swath of Portugal and northern Spain.
Figure 2. Forecast from the 1am EST 2/25/10 run of the GFS model for 18 GMT Saturday for surface winds. The GFS is predicting that Saturday's storm will peak in intensity at this time with a pressure of 974 mb. Sustained winds just below hurricane force of 60 - 75 mph (green colors) are expected offshore from Portugal. Image was generated using our wundermap for Spain with the "model" layer turned on.

this frozen drop was suspended on the thinnest filament of ice over our frozen brook..so very delicate and beautiful

I was just about to post the picture, too! They are pretty big iceburgs!
I find it interesting that the article's title pretty much says "The ocean currents will change!" but the article itself does not go into too much detail about it-- or at least the amount of details I was looking for. The explanation makes sense, but I was looking for more. I, for one, would like to know the likleyhood of this actually occuring.

I know ocean currents have changed in the past-- but I have not studied past changing ocean currents, so I don't know much about the reality (or gravity--or lack thereof) of the situation.
Just close your eye's and it will all go away.lol
Lol, I am not worried about it, I am just intrieged by it. Is the iceburg big enough and in the right location to really cause salinity changes? And have an effect on ocean temperature enough to have a greater overall effect?
Just curious, not worried.
Tow one of them babies up to the Gulf for hurricane season!
It's all mind over matter...
You don't mind, it don't matter....
Does anyone know anything at all about how to get an image to show up in the blog header (title) where it usually says "so-and-so's wunderblog".
I've done it before but years ago and now that I want to update it I can't figure it out. The normal img code doesn't work.

Statement as of 12:21 PM EST on February 26, 2010
... Record monthly maximum snowfall set at Central Park NY...
An all time monthly record snowfall of 35.9 inches was set at
Central Park NY as of 12:00 PM. This breaks the all time
snowiest month record for Central Park. The old record was 30.5
inches set back in March 1896.
Snow continues to fall... and the monthly total for Central Park will
be updated as the day progresses. Central Park snow records date
back to 1869.
Please refer to pnsokx statements for the latest available Central
Park snowfall.
Don't be too sure...a 60 mile long iceberg, 27 miles wide? That's a fair amount of water locked up
I will post an answer to your question in the latest blog. This one is old.
