September 1, 1926: Perhaps the most intense rainfall rate ever in downtown Minneapolis falls on this date. 1.02 inches of rain is recorded in six minutes, starting at 2:59pm in the afternoon according to the Minneapolis Weather Bureau. The deluge, accompanied with winds of 42 mph, causes visibility to be reduced to a few feet at times and stops all streetcar and automobile traffic. At the intersection of Second and Sixth Streets in downtown Minneapolis, rushing water tears a manhole cover off, and a geyser of water shoots 20 feet in the air. Hundreds of wooden paving blocks are uprooted and float onto neighboring lawns, much to the delight of barefooted children seen scampering among the blocks after the rain ends.
September 1, 1894: The Great Hinckley Fire. Drought conditions start a massive fire that begins near Mille Lacs and spreads to the east. The firestorm destroys Hinckley and Sandstone and burns a forest area the size of the Twin Cities Metropolitan Area. Smoke from the fires brings shipping on Lake Superior to a standstill.
September 1, 1807: The earliest known comprehensive Minnesota weather record begins near Pembina. The temperature at midday is 86 degrees, with a 'strong wind until sunset.'
Dry Into Saturday - Tracking Storms With Names
"We know that in September we will wander through the warm winds of summer's wreckage. We will welcome summer's ghost" wrote Henry Rollins. Ah September: prime time for foggy mornings and raging hurricanes.
Right now 4 different tropical systems are threatening the USA, including 2 hurricanes steamrolling toward the Big Island of Hawaii. Waters were once too chilly to support hurricanes in Hawaii, but that is changing as oceans warm.
A tropical storm forecast to hit the Florida Panhandle may track up the east coast this weekend; inland flash flooding possible from the Carolinas to Washington D.C. and New York City by Sunday.
Hurricane season peaks September 11, the date these pinwheels of trouble are most likely to make landfall, coinciding with peak water temperatures.
Nearly 8 inches of rain soaked the Twin Cities in August; 2016 is now on track to be one of the wettest years on record for much of Minnesota. Dry, comfortable weather lingers into Saturday, but we fall back into a wet rut next week. A series of storms may squeeze out 2-3 inches of rain in the next 2 weeks.
The map looks more like June 1 than September 1.
Kevin Hawkins asks:
"I noticed that the DNR shows no drought conditions anywhere in Minnesota right now. Is that unusual for this time of the year? It seems like it has been many years since that has happened."
Pete Boulay, at the Minnesota DNR and State Climatology Office answers:
We actually still have a very small area of "abnormally dry" or D0 designation still in far southwestern Minnesota O.K. it covers .13% of the state
"Below the map of Minnesota is a neat table that shows the percentage of drought coverage in the past. The last time Minnesota was free of any drought was back in July 2015, with a longer stretch after the really wet June 2014. Thus for the last couple of years we have had spells during the summer that have been drought free. The last time there was extreme drought (D3) in Minnesota was 2013. The last time there was exceptional drought (D4) in Minnesota was in the 1988 drought."
* Faint echoes of "Sandy" are ringing in my head - and although "Hermine" will not be as bad as Sandy, there is a growing potential for disruptive weather all up and down the East Coast from Friday into Sunday; coastal Georgia and the Carolinas right up I-95 into Washington D.C. and New York City may be impacted by 40-60 mph winds, flash flooding and coastal flooding and beach erosion as Hermine churns north.
* Blocking high pressure system over North Atlantic will act as a temporary road block, causing Hermine to temporarily stall off the Mid Atlantic coast, prolonging a period of pounding waves and heavy inland rains Friday into Sunday.
* Although impacts are not expected to rival Sandy in 2012, this may be the rough late-summer equivalent of a very severe winter Nor'easter. Areas along the coast that normally flood will probably experience water problems (Carolinas by Friday - Mid Atlantic region by Saturday into Sunday).
We'll update you again Thursday morning with an intermediate update Thursday evening. Remember the additional risk to the Big Island of Hawaii posed by Madeline and Lester (downgraded to Tropical Storms, but still capable of flooding rains and damaging winds). Map credit above: WeatherBell.

Here's an excerpt...
Summary: In the Lower 48, all eyes continue to be on Tropical Depression Nine in the Gulf of Mexico. This system still has the potential to strengthen into a tropical storm before making landfall sometime late Thursday/early Friday along the Florida Gulf Coast. Very heavy rain – on the order of at least 3-8” – will be possible across parts of Florida and Georgia over the next 72-96 hours as the system tracks over the region. Tropical storm force winds of 39 mph or greater will also be possible as well as storm surge of 3-6 feet or higher along the Florida Coast.
Preparations should continue across the region today, with conditions quickly deteriorating over the next 24 to 36 hours. In the Pacific, Hurricane Madeline will make a dangerous approach to the Big Island of Hawaii in the next 24 hours, bringing with it very heavy rain and the potential of hurricane force winds (74 mph or greater). Right behind that will be another system that could have an impact on the island chain into the weekend in the form of Lester. Another update on the systems Thursday morning.

Is Your Homeowners Insurance a Disaster Waiting to Happen? Here's a clip from Forbes: "...A less expensive form of coverage is cash value coverage, which may not include the added rebuilding costs. Natural disasters, such as hurricanes and tornadoes, can cause widespread damage resulting in shortages of building materials and labor, significantly driving up the cost of rebuilding. It is a good idea to make sure your policy coverage limits are sufficiently high to account for these higher replacement costs. Your policy may also include or make available guaranteed or extended replacement cost coverage to protect against these unexpected cost increases. Read the policy and know what you own. Replacement cost and cash value mean different things in the insurance world..."

Placing charging stations at workplaces, where cars spend much of their time, will be uniquely powerful. When a workplace installs a charging station, employees are 20 times as likely to buy a vehicle with a plug, according to a survey from the U.S. Department of Energy.Graphic credit: " "

Making a profit is essential in business," Mark Wilson, chief executive of Aviva, said in a media note on the Overseas Development Institute's (ODI) website. "But we will only be in business in the future if we act sustainably and create wider long term social value. That's just good business – and not acting sustainably is very bad business indeed." "Climate change in particular represents the mother of all risks – to business and to society as a whole," Wilson added. "And that risk is magnified by the way in which fossil fuel subsidies distort the energy market. These subsidies are simply unsustainable..."

The "Social Cost of Carbon" Is The Most Historic Climate Change Decision Yet. The Daily Beast has details: "One of the most significant court cases about climate change was decided earlier this month by a federal appeals court in Chicago. Given that it was steeped in the enervating context of refrigerator regulations, you may have missed it. But amid the stultifying discussions of compressors and insulation foam was a crucial advance in our nation’s belated attempts to forestall global climate catastrophe. It all comes down to a new phrase: the Social Cost of Carbon. Here’s why it’s important. By law, government agencies—in this case, the Department of Energy—are often required to show that the benefits of a proposed regulation exceed the costs..."
