One or two panels out of how many? This info is more useful than if the whole fence fell or was not damaged at all by the wind.
Use this to figure the force on the panels
but you may have trouble finding the pull-through force for hardwood/softwood boards for some screw head or washer diameters.
In that case, run an experiment using one or more people to simulate the wind force by standing on the loose & damaged panels, and try different size washers. Each doubling of the washer diameter increases the pull-through force by 4x. You may have to prime & paint fender washers for this.
You want the fasteners to hold 4x or more of the max expected tensile force due to wind. For your area there may be max predicted wind speeds that are not exceeded 90% or 95% of the time, see below.
Once this is fixed you may find out what is the next weak point in the fence structure.
SOURCES OF CLIMATIC DATA ON WUNDERGROUND
Hourly historical weather conditions are available for each day back through the beginning of records for most U.S. cities(as early as 1900) by using the drop-down menu under "History & Almanac". Set a date and hit "View".
"History & Almanac" is located on our local weather pages below the Current Conditions and Forecast sections under the title "Nearby".
We also provide a comma-delimited format. Click the link just below the tabular data to view the "CSV" format text.
You can also view our "Calendar View" "Yesterday's Official Weather and Almanac", and "Seasonal Weather Averages" there.
We also provide data from personal weather stations that can be found at the bottom of local forecasts pages. *Many of these station have historical data available.
OTHER SOURCES OF CLIMATIC DATA
The best source of climate data for the world is the National Climatic Data Center, located at:
The NCDC "CLIMVIS" option is a free way to get daily, monthly or yearly (but not hourly) data, see:
Click the button "I agree to terms", then click on the map presented to start choosing which data location you want to plot data for.
If you need more detailed data, you may have to pay money. Many of their products are free only to ".edu" domains, for more info check out:
1) There are 6 regional U.S. climate centers:
High Plains: ***http://hpccsun.unl.edu/
2) Many local National Weather Service (NWS) offices keep some climate
data for their region on their web page. See
for a list of all the web sites
of local NWS offices.
3) Check if a public library in your area has the serial publication
"Climatological Data". This monthly is published for each state and lists
all official temperature, precipitation, snowfall, evaporation, soil
temperature, etc. daily observations from the many weather stations in
4) There is an excellent book called "The Weather Almanac" which
has climatological data for 100 cities across the U.S. You should be
able to find this at your local library.
5) A web alternative to "The Weather Almanac" can be found at:
It has climate data for many US cities in a point and click interface. *It is a great alternative to a weather almanac for looking up average temp, precip and snowfall, plus, many states have very cool "relief" maps as the top level, so you get a sense of the topography of the state.
6) Canadian climate data:
7) International climate data:
This site has links to the weather services of over 60 countries. Some of these weather services have climate data for that country. Also,
has climatic temperature and precipitation data for most world cities.
8) Sunrise/Sunset, Moonrise/Moonset, Moon Phase, Moon illumination, Eclipses in the future or past:
9) Wind Rose data showing climatological values of wind speed and direction for 237 U.S. cities can be found at:
