[MAIPC] 03/02/18 Weather Alert: High Wind Warning

Fri Mar 16 07:13:40 PDT 2018

Marc,

Have you worked up a presentation on trees weakened by invasive vines? I would be interested in reading anything you have put together.  I know you had talked earlier about this being a prime topic for research. 

Thank you for raising this issue!

At the Strawberry Hills Civic Association meeting on March 12 and at the Maryland Invasive Species Council meeting yesterday I reported that studies indicate that we can prevent about half of the trees from falling down over highways during a major storm for about 10% of the effort to control them all. It just takes 10 minutes to cut stump the non-native invasive vine, such as oriental bittersweet, at ground level and apply glyphosate to the cut stump. At the SHCA meeting it was reported that trees came down over electric power lines causing the electric power outage and subsequent brush fires.

Marc,

Wind load was assuredly a factor for vine-laden trees, evergreen ivy or not.  I personally observed 4 downed obstructive roadside trees in my travels on state or county roads in 2 counties that Friday.  All White Pines.  No surprise there.

To my knowledge, no, SHA has not conducted such a study. However, NCHRP is proposing a research study to develop protocols for removal of hazardous trees along the roadside.  It may not specifically address vines, though.

Thanks for asking.

Shelley

Dear Shelley 

Has SHA done such a study? Thanks

Excellent idea.

I did a study of the first 5 trees I found that had fallen down over highways causing traffic to stop because of the Friday March 3 wind storm. The first was strangled by oriental bittersweet, the second by oriental bittersweet, the third no vine found, the fourth American Grape, the fifth Japanese honeysuckle. About 8 years ago 7 trees came down in a February storm. All were strangled by English Ivy in a 30 acre park. No other trees came down. 

So let us do a statistical study after the next gross storm.

I have not yet seen trees come down in the parks where volunteers removed all the non-native invasive vines that would otherwise strangle and weaken them, including English Ivy, Oriental bittersweet and Japanese Honeysuckle. Would it have cost less for our government to have spent the $ with preventive care than what it cost yesterday restoring roads, buildings and hospital visits.

Potential Hazardous Weather Conditions

The National Weather Service has issued a High Wind Warning for Prince George’s County and Montgomery County, which is in effect from 7 AM Friday to 6 AM EST Saturday.  The strongest winds will be Friday afternoon through Friday evening, and are predicted to be 25 to 40 mph, with gusts around 60 to 70 mph. 

Individuals and M-NCPPC facilities should prepare for the possibility of damaging winds that may blow down trees and power lines.  Also, widespread power outages are expected. Travel will be difficult, especially for high profile vehicles. 

Staff is asked to monitor forecasts and be prepared to take action should warnings be issued.  

Preparing for Strong Wind Gusts:

*       Bring Loose Items Indoors.  Objects left outside in wind storms can either become projectiles and potentially injure people and property, or the objects themselves can be lost, damaged, or ruined. It is important to remember that nothing is more important than the safety of people, so objects should only be brought indoors if it is safe to do so.

*       Secure Large Outdoor Objects.  Some objects will simply be too big to safely bring indoors in the event of high winds, but even if they are too large to bring in, they can still be affected by wind. If possible, these items should be anchored and secured.  Objects to consider include signs, tables, chairs, large umbrellas, play structures, watercrafts, garbage cans, and much more. There are many ways to safely secure these objects, including weights, ropes, chains, and stakes.

*       Close and Secure Doors and Windows.  Closing windows and doors is a simple step that can be easily forgotten while everyone is securing objects, collecting their belongings, and heading indoors. Open windows can result in water damage or broken glass. If there are shutters, it is important to close them. Also, close and secure doors since strong winds can easily rip them from hinges.

M-NCPPC Notice 11-08 <https://www.mncppc.org/DocumentCenter/View/5772>  Please see M-NCPPC NOTICE 11-08, “Preparation, Staffing, and Compensation During Emergency Conditions,” <https://www.mncppc.org/DocumentCenter/View/5772>  Which outlines further steps to follow in the event of a weather emergency.

In the event of an accident or injury, call the Risk Management and Workplace Safety Office as follows:

*       During regular hours

301-454-1686 or 1692

*       After hours 

301-275-5125 or 240-393-0419
