Record rains and flooding swamp Rhode Island and Massachusetts

Record rains from a slow-moving and extremely wet Nor'easter have triggered historic flooding in Rhode Island and Southeastern Massachusetts, with several rivers exceeding their 100-year flood levels. The 16.32" of rain that has fallen on Providence, Rhode Island, this month is the most rain recorded in any month, besting the previous record of 15.38" set in October 2005. Blue Hill Observatory in SE Massachusetts also set a record for wettest month ever, with 18.79" (previous record: 18.78", August 1955.) Records extend back to 1905 and 1885 at the two sites. The Rhode Island all-time state record for heaviest precipitation in a month was smashed as well, thanks to the 19.62" observed this March at North Kingstown. The old state record was 16.70", set at North Foster in October 2005. Many locations in the Northeast recorded their wettest March ever, including New York City and Boston.

From a historical perspective, river flooding in parts of Rhode Island and eastern Massachusetts is expected to rival or exceed the all-time record floods of August 1955, when Hurricanes Connie and Diane hit within one week of each other. Several rivers in the region that set their all-time flood heights just two weeks have set new records this week. It's pretty remarkable that we are having record rainfall and record flooding in the cold season month of March. It's much easier to set records in August, when there is much more moisture in the air available for record rains.

Here is a summary of the major flooding occurring, courtesy of the National Weather Service:

* Pawtuxet River in Rhode Island...flooding will exceed what occurred in middle March. Record-shattering flooding is forecast along the Pawtuxet River through Thursday. Records at the Cranston gauge date back to 1939.

* Blackstone River in Rhode Island...flooding at Woonsocket is forecast to be the worst flooding since the flooding associated with Connie and Diane in 1955. However...due to the heavier rains which have fallen below Woonsocket...flood impacts approaching the 1955 event may be realized.

* Charles River at Dover Massachusetts...near record flooding is forecast. This is expected to be the worst flooding since the flooding associated with Connie and Diane in 1955.

* Neponset River at Norwood Massachusetts...major flooding has already occurred...with a crest of 11.2 feet. This crest is well below the record crest of 14.65 feet which occurred in August 1955 with Connie and Diane.

* Sudbury at Saxonville Massachusetts...record flooding is forecast. This will be the worst flooding since the April 1987 flood.

While the storm responsible for the rains has moved out to sea, there will be a prolonged period of urban and small stream flooding...which should last for at least a couple of days. To keep track of the flood situation, use our wundermap with the USGS river layer turned on.

Severe weather season is here
Two tornadoes occurred near Charlotte, NC on Sunday, March 28, 2010. One of these twisters passed within a few miles of one of the FAA's high-resolution TDWR Doppler radars. Our tornado expert, Dr. Rob Carver, has written an excellent post showing high-resolution images and animations of this tornado.

I'll have a new post on April Fool's Day.

85 to 88 Friday thru all of next week in Orlando. Also, will begin to introduce isolated to scattered seabreeze thunderstorms later next week as the humidity is really going to build over the next few days.

seriously though,its impossible to predict a storm that far away and the end of june begining of july is FL's hottest time of year,not may...historically speaking(right before fl's rainy season which is usually july-sept)


Sorry man, but you need to get a clue! First that is TS IDA from last year and second our rainy season in Orlando starts May 26th not July. Due your research before you attack. I'm surprised I wasted my time quoting you. My opinion is from what I'm seeing is that we may have a storm in the western caribbean come late May.

It was the tube guy and Masters' daughter, that was it. Get off your kiesters and call dammit. I'm not calling because I'm a social person, not a meteorological whiz. And have nothing intelligent to say. So c'mon.

Inexcusable, but he has always added life to the blog. Those, and other types of posts, are far and few between.

Did I just excuse him? ;)

To me, come on and have some fun, especially since we all know exactly what it's all about. No need for him to do that, really. Win-win.

He'll be baaaack. (Arnold voice)

Levi, Lefty's a hoot! He came in briefly this past winter with pics of himself in one of the many weird snowstorms...it was fun to get to meet him, as I was not lucky enough to be here in the good ol' bad ol' bad hurricane days of '05 etc.

Yeah, Chicklit, I don't understand at all the plagiarizing on a blog instead of just giving a credit or attribution...shoot, it's easy enough, we all do it for research papers, and we're not going for a Ph.D. here -- just trying to get accurate info out and maybe have some good discussions and exercise some brain cells.


Wow lol I didn't know he ever came on here after that.

Looking back.....it was pretty funny lol. This was when TD 10(Katrina) was just developing.

Lefty liked to disagree with everyone and his grammar along with stormtop's was just hilarious. The discussion continues on several of the previous pages of that blog. The annoying thing is Stormtop's radical prediction for Katrina came true nearly perfectly, except for the trajectory at landfall.

I seriously think we're in for another 2009.

I'm going with 5.5 for SSIG's scale.

So I don't jinx it, though, 20/10/5 is my prediction, contrary to the 5.5.

Last year for me, off the top of my head was 16/5/2.

Oh what I'd give to have another fight with Stormtop instead of an AGW argument lol. I actually really enjoyed beating up trolls. If I wasn't caught up in being too immature, I could sometimes tie them up so tight they couldn't think of anything to say. Kept things interesting....

Another guy I remember is Lefty420, but I can't quite recall how much of an expert he was on the tropics. I remember he and Stormtop were arch-enemies and argued constantly, but how much accurate info was in those arguments, I'm not sure. I'll have to look that up and see. One thing I do know, is that he had very poor grammar lol. Stormtop and his capitalz wasn't far behind him either.

The most memorable part of last hurricane season was Ike posting "More Nothing" every day from the NWS site and Patrap posting his "Nuthin" cartoons. That pretty much summed it up. Then there was Weather456 keeping everything going and interesting with his analysis of what little there was going on. I think we exhausted him with that. He really was a hero last year. And this year he's having a baby!


I know! I'm happy for him :) He will be sorely missed though. He had an amazing knowledge of tropical waves and how to analyze them over Africa. That was his biggest strength.

Lol yeah I bet, and now that I think about it that's exactly why there were probably no trolls either. They will come out if there's a big storm threatening the U.S. or an active season getting underway.

I found GulfScotsman entertaining.
(caricature of the drunken sailor), at least he played that role even if he became a big abusive at times...and went over the top.
I find the characters on this blog as interesting as many I've met in real life.
By the way, I think Jeff Masters must like you Levi, for your tenacity and willingness to study. You are also good at telling others what is going on.
Just decide what you're going to do and go with it. Not everyone will ever agree with you anyway, so you might as well do what your conscience dictates.


Oh yeah it's been downright entertaining on here at times.

Well thanks Chicklit, but I can't imagine the doctor having any fondness for me lol. I will indeed continue to find my own way....I don't care much for following the consensus just because it's the consensus. We'll all keep learning more and hopefully get closer to the truth.

after this summer ice extend will be the lowest of all just because ice extend is in a rebuilding phase most is first year ice or as my grandfather would call it slop ice mostly slush fast melting quick to form fast to thaw


Yeah, this summer will likely dip below normal again, but the fact that the winters are holding their own does mean something, and it will be worth watching as we head into a La Nina this winter, which should translate to more sea ice overall during the following 2-3 years.
