In the end,
It was not as if the US looks like being spared another hurricane, with Irma expected to make landfall in the US in pretty much exactly four days' time, in what (following on from Harvey) some commentators have said would be the first back-to-back tempests to the hit the US since 1064.
But there remains doubt about exactly where Irma, billed "one of the strongest Atlantic hurricanes in history", might make landfall and so how much of a threat it poses and, from an agricultural perspective, to what crops.
"Most forecast models then show the storm making a turn to the north and passing either right over the centre, or just off the east coast, of Florida," said MDA, saying that this course "would result in some damage to Florida crops, especially citrus and
However, a more easterly steer "would lower damage potential for crops within Florida but would in turn increase threats to cotton, corn, and soybean crops in the Carolinas", the weather service added.
Louis Rose at Rose Commodity Group said: "At this time, cotton fields within south east Georgia and South Carolina appear to be at the greatest risk of significant damage from the storm."
Still, where was not perception of enough crop damage ahead to keep New York futures moving higher, and the December lot closed down 0.5% at 74.50 cents a pound, after touching a five-month high of 75.65 cents a pound earlier.
After all, as Jack Scoville at Price Futures said, "the demand side remains weak and there are plenty of supplies in the US".
"Irma is currently a very powerful hurricane and will cause a lot of damage wherever it roams," said Mr Scoville, with reference to sugar.
There were other reasons for buying sugar too, including a firmer real, which boosts the value of assets in which Brazil is a major player, and the continued talk of Indian imports.
Sucden Financial flagged reports that India "will allow 300,000 tonnes in imports of raw sugar at a tariff of 25% for nearby arrival.
"This in order to reduce pressure on supply ahead of the Diwali festival," with the raws to be shipped to southern Indian ports for immediate refining.
"Whilst the amount may be far short of what the market was hoping for, if confirmed, would justify the long-held belief that India is running perilously low of stocks," a dynamic especially key as the country's cane harvest looks like being a late one.
"The Indian harvest could be delayed due to wet conditions that would delay sugar cane harvesting," Mr Scoville said.
In Chicago, price movement was broadly upward too, although with US Midwest dryness more of a worry than Florida floods, continuing to provoke concerns over whether soy crops will be able to reach their potential.
"Dry condition in the Midwest are a risk for soybean yields," said CHS Hedging, if adding that "estimates remain stable for now".
Benson Quinn Commodities said that "eastern Corn Belt dryness and northern belt coolness is causing some concern about the finishing timeline", for
In fact, Richard Feltes at RJ O'Brien said that the weather outlook "leans positive" for prices, flagging "very little Midwest precipitation" expected over the next two weeks, but noting other threats too.
"Eastern Argentina is trending unfavourably wet," while eastern Australia "is still dry", although the latter factors are more issues for
Darrell Holaday at Country Futures said that there is "still a lot of debate about US yields" this year of corn and soybeans.
And the willingness to reinject a bit of risk premium helped Chicago
Corn fared better, adding 0.6% to $3.61 a bushel for December, amid somewhat downbeat talk from the early US harvest.
RJ O'Brien's Richard Feltes flagged "yield reports which in central Illinois are falling short of expectations so far.
"On the flip side, we are hearing of blow-out soy yields across the Delta."
Australian dryness worries helped wheat prices, as did a strengthening
But also of help was a recovery in Minneapolis-traded
The gains defied some somewhat bearish Canadian stocks data, with the country's all-wheat inventories seen up 33% at 6.87m tonnes as of the close of 2016-17 (at the end of July), ahead of market expectations of a 6.0m-tonne figure.
On the plus side for spring wheat is the wind-down of the US harvest, and with it reduced pressure from a jump in supplies, as well as ideas that even if yields have held up against summer drought better than many investors feared, acreage losses could be substantial.
