The tree appears to have some white rot in it, most likely due to
unspecialized colonization, not heart rot, beyond that we do not know much
about it.  The idea of epicormic shoots may be wrong as I believe the tree
is *Ulmus pumila* and as such adventitious buds and shoots are very common.

We do know that there was widespread tree damage across New York State and
Ontario that night (and maybe beyond?).  I have seen hundreds of damaged
trees on my routes over the last week.

Wind speeds have been reported as 50-80 kph and gusts as high as 120 along
Lake Ontario.  With these speeds we see breakage of defective trees and
some "perfect" trees.  Why perfect. well some species, Norway Maple and
Bradford Pears, still had leaves so wind loading was high, particularly
with the dense damp air.

How does one assess this type of failure in advanced? A competent person
performs a through ground-based VTA and recommends aerial or advanced
inspections as necessary.  That is not a great mystery but in general
advanced assessments are not commonplace, a level 1 or level 2 as defined
by TRAQ is the standard.

your example Were the neighbours concerned about a visible tree defect or

I hope the girl makes a full recovery btw.

Here it is. Of course there's insufficient information to come to a
conclusion, but the location of the break on the trunk in relation to the
apparent growth from dormant (epicormic) buds might have relevance or be a
coincidence. Apparent heart rot.

The question is, how does one best assess this kind of failure in advance?
