Storm's Corners (Ont) EF2 Tornado

AWCN11 CWTO 111114
Updated weather summary for all of Southern Ontario and the
National Capital Region issued by Environment Canada
At 7:14 AM EDT Tuesday 11 September 2012.

8th tornado of the season confirmed.

At around 10 AM on Saturday, September 8, a damaging storm moved
through an area near storms corners in Eastern Ontario. Storms
corners is approximately 10 kilometres to the east of Napanee. An
Environment Canada employee performed an on-site investigation
earlier Monday, viewing damage and talking to eyewitnesses. Upon
completion of the investigation the event was deemed to be a low end
Fujita scale 2 tornado with peak winds between 180 and 210 kilometres
per hour.

The tornado occurred in the withers road area to the southwest of
storms corners. The damage included an 8 metre trailer weighing
approximately 2500 kilograms. The trailer was carried and rolled over
30 metres by the tornado and totally destroyed. A new and
well-anchored storage shed was destroyed to its foundations. The roof
from this shed was carried approximately 150 metres and fell to the
ground almost intact. In an example of quick thinking and appropriate
action, a man in the shed at the time the tornado struck immediately
took shelter under a heavy workbench and avoided serious injury as a
result. Debris from a barn originally at the western end of the
damage track was carried over 4 kilometres. Numerous trees in the
area were uprooted or severely damaged and a number of large branches
were driven into the ground by the force of the tornado. Debris from
damaged or destroyed buildings littered surrounding fields. Farm
machinery weighing as much as 1000 kilograms was carried as far as
100 metres. In total, the damage path was around 6 kilometres long
and about 150 metres wide, at its widest point.

This is the 8th tornado of the season in Ontario. Ontario normally
has 13 tornadoes each year in a season that runs from late April
until early October.

Makena Cloud, Maui, Hawaii

I know what the "Makena Cloud" is, but I am interested in better understanding the phenomenon behind the meteorological conditions that prevail to create this cloud daily, it's scope of impact both north and south of Big Beach/Makena Beach, and how long it lasts daily (develops at X-time and dissipates at Y-time).
