text-decoration-style: initial; text-decoration-color: initial;">On
August 10, 2020, a severe weather phenomenon known as a derecho
developed over the Midwest, forming near the border of South
Dakota and Nebraska. It traveled 770 miles at an average speed of
55 mph over five states before eventually dissipating over eastern
Indiana and Ohio. Derecho means straight in Spanish and describes
the fast moving and long lasting high straight-line speed wind
storms that can generate hurricane force winds and produce
tornados within the thunderstorms. While uncommon, they are
generally most prevalent in the northern hemisphere during the
months of June, July and August.</p>

text-decoration-style: initial; text-decoration-color: initial;">Wide
swaths of the Midwest were affected, but the most severe damage
occurred in several different areas along its path. The highest
estimated wind speeds reached 140 mph (equivalent to a Category 4
hurricane) and took place over Iowa. One of the amateur stations
that sustained heavy damage was the contest station of Toni
Radebaugh, N0NI, located near Rippey, Iowa. The weather forecast
for that day included a 30 percent chance of rain with no mention
of severe storms. The storm arrived at around 11 AM. In the
roughly 30-40 minutes that followed, ten towers were either lost
or severely damaged affecting a total of thirty-five HF Yagis.
With area winds estimated in excess of 100 mph, many trees,
including seventeen 100-year-old cedars on the west side of the
towers (and just out of view in the photos) snapped and landed on
multiple guy wires. This caused the towers to bend and break,
bringing down the towers, antennas and other nearby towers that
may have been in the way. The towers and antennas outside of the
tree line were not affected, including a homebrew full-size
3-element 40 meter Yagi at 196', a real testament to the robust
design of the towers and antennas at Toni's station. Toni stated
that he had not lost a tower in 43 years, but when he finally did,
it was spectacular.</p>

text-decoration-style: initial; text-decoration-color: initial;">In
addition to the tower damage, trees came down on the house and the
surrounding corn fields were crushed by the winds resulting in a
total loss of much of this year's crop.</p>

text-decoration-style: initial; text-decoration-color: initial;">Toni
vows to rebuild a number of towers and antennas as that is his
favorite thing to do in Amateur Radio. This time, they may not go
up as high, and of course, they'll be spaced farther away from the
remaining trees.</p>
