Rockland-Sparta, WI Monroe-Juneau-Wood Counties Damage Reports

During the afternoon of May 22, 2011, strong to severe thunderstorms developed ahead of a cold front across southeast Minnesota, northeast Iowa, and western Wisconsin.  These thunderstorms produced large hail, damaging winds, and six confirmed tornadoes.  Between 1:18 p.m. and 6:19 p.m., there were 11 Severe Thunderstorm Warnings and 11 Tornado Warnings issued by the National Weather Service in La Crosse, WI.  Seven of the eleven Tornado Warnings were issued on a severe thunderstorm which moved from northern Howard County (northeast Iowa) northeast into Portage County (central Wisconsin).  Average lead time on the tornado warnings was approx. 13 minutes.

There were a total of 6 tornadoes in our area, including three EF2 tornadoes.  One of the EF2 tornadoes hit La Crosse, WI and produced damage from river to bluff on the south-central part of the city.  It was the first tornado to hit La Crosse since 1966 and perhaps one of the strongest ever to the area.  Wisconsin had 11 tornadoes on May 22, 2011 which was the 2nd most ever for any day in May.  Besides a few minor injuries, impact from the storms was mainly property damage.

The map below shows the warnings (red boxes are Tornado Warnings and blue boxes are Severe Thunderstorm Warnings) that were issued along with severe weather reports (red circles are tornadoes, yellow circles are hail, and cyan circles are wind reports) received.

The first tornado that developed on Sunday, May 22nd, 2011 started 4.2 miles northeast of Riceville in Howard County, Iowa at 2:33 pm.  The first damage was located along Dale Avenue about 3 miles north of Highway 9.  The tornado immediately increased to EF1 strength with winds near 100 mph and a path width of 100 yards.

Damage consistent with upper EF1 scale tornadoes, winds of 100 to 109 mph, occurred as the tornado tracked northeast.  Several farms had outbuildings destroyed, widespread severe tree damage, and several homes had partial or complete roof damage.

As the tornado passed south of Chester, Iowa around 2:50 pm, it reached its maximum width and strength.  A location two and a half miles south of Chester had upper EF2 damage consistent with winds around 130 to 135 mph.  Another farmstead 1.6 miles southeast of Chester had EF2 damage with winds estimated near 120 mph.  The width of the tornado was estimated to be between 250 to 300 yards wide at this point.

As the tornado crossed into southern Fillmore county, it weakened slightly but remained rather wide at 200 to 250 yards.  A location 7.7 miles southwest of Harmony, along with another farm along Highway 44 about 4 miles west of Harmony, saw upper EF1 damage with winds estimated of 105 to 110 mph.  The tornado occurred in this area between 3:05 pm and 3:15 pm.

The tornado then weakened rapidly to EF0 strength as the path width narrowed to around 50 yards as it tracked about a mile north of Harmony, Minnesota.  The last damage, which was rated EF0, occurred around 3:25 pm about 2 miles northeast of Harmony.

The total track length of this tornado was 28 miles long with a maximum width of 250 yards.  The strongest damage was rated a higher end EF2 with winds of 130 to 135 mph.

Houston County, MN Tornado Damage (connected with La Crosse Tornado)
Start/End location Estimated Time Path Length: Max Width: EF Rating:
5 miles SW Hokah to La Crosse 4:00 pm to 4:28 pm 16 miles 150 yards EF2

The first indication of storm damage was noticed in central Houston county about a half mile west of the intersection of Highways 22 and 76.  Damage was to a few medium sized trees 20 to 40 feet in height and about 2 feet in diameter that were uprooted or snapped off about half way up.  This damage is consistent with high end EF0 to low end EF1 damage with winds estimated at 80 to 90 mph.

The most significant damage, which was tornado related, was observed at a farmstead about 5 miles west-southwest of Hokah.  Numerous trees, some 100 feet in height and 3 feet in diameter, were uprooted or snapped halfway up the trunk.  Significant damage to a couple houses, barns, and out-buildings indicated damage consistent with low end EF2 tornado damage with winds estimated at 105 to 120 mph.

A damage pattern was again detected farther to the east, approximately 1 mile west of Hokah along Highway 44. 2 barns were significantly damaged and a residence received minor damage.  This damage was given an EF1 rating with wind speeds of approximately 95 mph.

In the community of Hokah, roof damage to a residence on the south side was observed along with extensive tree damage. This damage was also given an EF1 rating with wind speeds estimated to be around 95 mph. 

From Hokah to the Highway 26 bridge over the Root River, approximately 3 miles northeast of Hokah, extensive tree damage was observed resulting in a damage rating of EF0.  At this point, the damage path entered the Mississippi Floodway and continued toward the city of La Crosse, WI.

La Crosse, WI Tornado (continued from Houston County, MN)
Start/End location Estimated Time Path Length: Max Width: EF Rating:
5 miles SW Hokah, MN to La Crosse, WI (on Wedgewood Drive East) 4:00 pm to 4:28 pm 16 miles 150 yards EF2

The tornado that originally began southwest of Hokah, MN (Houston County) crossed the Mississippi River around 4:20 pm near Target Lake and entered the city of La Crosse shortly after on the south side of the city near Green Island Park and the southern side of Isle La Plume.  About 20 to 30 mature Oak and Silver Maple tree trunks were snapped off about 20 to 30 feet from the ground along the initial path.  A residential area was then struck, with damage to housing structures including partial roof removal and heavy garage damage.  A two-story apartment building on Cook  and 7th Street had a portion of its roof completely removed with a second story side wall missing.  The damage was given a lower end EF2 damage with winds estimated to have been about 115 to 120 mph.  Significant tree and power line damage was also seen in this subdivision.  The Green Island Ice Arena sustained the highest end damage on the entire path with the tornado width approximated at 150 yards wide.

The path continued northeast, with damage to a small industrial area at the intersection of West Avenue and Green Bay Street.  Roof collapse because of a side wall collapse was noted at two businesses.  One small apartment building had a roof cleanly removed.  Wood power poles were leaning over with one of them snapped.  There was widespread damage to mature trees in the area as well.  This portion of the track was given an EF1 rating with winds estimated at about 100 to 110 mph.  The tornado was more narrow in this area at less than 100 yards wide.

The tornado continued northeast through the city with mainly tree damage and light roof damage to shingles and trim.  The width was less than 100 yards at this point.  The tornado turned slightly toward the east-northeast near East Avenue, and continued through the Losey Avenue and State Road intersection where a K-Mart roof sustained damage and power lines and street lights were downed.  The tornado continued east-northeast into a residential area, where mainly tree damage and structural damage from fallen trees occurred.  The tornado then had brief touchdowns along a skipping path from the end of Farnum street eastward over the ridge and into Wedgewood Valley. In Wedgewood Valley, on Wedgewood Drive East, a cluster of tree damage was found. This stretch of damage was rated EF0 to EF1 with winds estimated at 80 to 105 mph.

The total tornado track length was 16 miles and was on the ground for approx. 28 minutes.  The maximum width of the tornado was 150 yards and the strongest damage was rated lower end EF2 with winds of 115-120 mph both in Houston County, MN and on the south side of La Crosse (near Green Island).

Monroe-Juneau-Wood Counties, WI Tornado
Start/End location Estimated Time Path Length: Max Width: EF Rating:
4 miles NW Tomah to 3 SW Nekoosa 5:15 to 6:05 pm 37 miles 800 yards EF2

Damage was first noticed about 4 miles northwest of Tomah near Elder Road.  Initially an EF0 tornado, it crossed Interstate 94 north of Tomah.  It proceeded east-northeast causing significant damage to a house along Dolphin Road northeast of Tomah. This area experienced EF2 damage with wind speeds around 120 mph. The path continued through mainly wooded areas between Tomah and Mather crossing Highway 173 about 3 miles southwest of Mather.

The tornado track crossed County Road H and entered the west side of the Necedah National Wildlife Refuge between Mather and Finley.  The tornado began to increase in intensity and size, but still was an EF1, causing mainly damage to trees.

About a mile and a half south of Finley, the tornado crossed Highway 80 and continued to grow in size.  The damage path was a half mile wide as it approached County Road F east of Finley.   Many trees were snapped or blown down along and near County Road F, some falling on nearby homes.

Another area of EF2 damage was noted to a cranberry business east of Finley where nearly all outbuildings and sheds were demolished and tossed into nearby fields.  A loading deck platform along with trucks were heavily damaged.  Thick wooden power poles were snapped or sheared off for a half mile stretch.  Other nearby homes had minor damage.

The tornado continued northeast toward the Wood-Juneau county line and weakened as it did.  Mainly EF0 damage was noted to mainly trees with some minor roof or siding damage.  A bulk of the tree damage was related to winds around the side of the storm as it moved into Wood county Wisconsin, south and southwest of Nekoosa. The Green Bay NWS has conducted a survey in Wood county, which can be read here. Our offices will collaborate to decide if tornado paths match up to where it was just one long tornado.

The total tornado path length was at least 37 miles with a maximum width of 800 yards.  The strongest damage was lower end EF2 with winds estimated at 120 mph.
