Although since 2015 at least the Polar Bear Alert Program in Churchill Manitoba usually issued and published its problem bear reports weekly during the ice-free season, this year has been an odd exception. Two reports in early July, then nothing. Yesterday, there was a dump of reports that had been compiled on 1 September and 7 October, according to their metadata.
There are still a few weeks missing, including the two most recent weeks but at least now we have a more complete picture of what’s been going on with problem bears in The Polar Bear Capital of the World that can be compared to previous years. Such reports in various forms go back to the late 1960s, although only those from recent years have been publicly available (Kearney 1989; Towns et al. 2009).

Also, note that a mother with a litter of triplets spotted along the coast of Wapusk National Park (just east and south of Churchill) in good condition, 15 September 2020 (see photo below). Biologist Nick Lunn falsely claimed in 2018 that no triplet litters had been born in Western Hudson Bay since 1996 – a correction made later claimed Lunn meant there hasn’t been any triplet litters seen in the fall, which was also not true in 2017 or in 2020:

This is week 15 for most polar bears onshore near Churchill in Western Hudson Bay, which means they have been onshore for almost 4 months. Still, photos being circulated are still showing bears in excellent condition and we are just waiting to see if freeze-up this year is as early as it has been for the last two years.
Polar bears that have come off the sea ice of Hudson Bay near Churchill, Manitoba in Western Hudson Bay are apparently in a wide variety of conditions, from very fat to skinny. So, not all skinny despite the relatively early breakup of ice in the northwest.
Most of the ice was gone from the NW of Hudson Bay for the week of 23 July 2018 and the graph below shows that this is a new pattern that began in 1997, with only 2009 being an outlier:

Comparing Churchill problem bear statistics over a few years provides some critical perspective: this year, the bears are causing much fewer problems.
This 2nd week in September is no exception, being the 9th week ashore in all cases: 2017 (4-10 September, where I think “total number of polar bear occurrence reports to date” should be 64, not 53, see week 7 report here), 2016 (5-11 September), 2015 (7-13 September), where there were about 1/2 the number of bears in “jail” this year compared to the last two years (i. e., 6 vs. 11 and 12) and slightly more than 1/2 the number of occurrence reports in 2017 than in 2016 and 2015 (64 vs. 107 and 99):
Latest report on problem bears in Churchill, Manitoba, from the town’s Facebook page.
Polar Bear Alert Program Activity Report as of Oct. 19 (click to enlarge):
30 polar bears handled to date this year; 11 bears in the holding facility this week (6 released, including a sow and two cubs). As mentioned in the new Polar Bear Town reality TV show, Churchill officials have been more vigilant and pro-active since the two polar bear attacks in 2013 than they were previously, capturing any bears than come close to the town.
