When should you be scared of a tree during a storm?
We speak in terms of risk, so there is no numerical system (1-10) or a classification as dangerous or safe. There is no such situation as zero risk, but there are situations that increase your risk.
First, we look at Target (not the store). Targets are anything a tree or tree part could hit or affect. This may be a person, a vehicle, a house, a piece of equipment, etc... Anything can be a target. Some are more valuable than others. Some targets can be moved, such as a vehicle or a picnic table. Others are stationary, like a house.
Next, we look at the tree for conditions of failure, which may be dead limbs, bark inclusion (2 or more trees, trunks, or branches in close proximity - they push apart), cut roots (roots are very shallow), soggy soil, overextended branches, internal decay, etc... We won't have time to inspect your trees before a storm, so we want you to be able to recognize common defects and likelihood of failure, combined with the size of the tree part(s). If you have any of these defects, you may not be able to move your house, but you can move your mobile property and your selves. Some structures provide great protection from tree failures; others not so much.
We look at likelihood of impact. Will the tree or tree part hit the target? Normal weather would include targets within reasonable striking distance based on the length of the tree or part. In extreme weather, wind could carry trees for a great distance before striking a target. You cannot predict prevailing wind direction; please don't make that mistake.
Then we look at the consequences of damage: if the tree or tree part strikes the target, what damage would occur? This ranges from a scratch, an inconvenience, a broken bone, a damaged roof, all the way to a flattened house or death.
Ultimately, we combine the matrices of likelihood of failure, impact, and consequences to arrive at a risk rating. That being said, we generally do not assess trees for extreme weather (hurricane, tornado, earthquake, tsunami, etc...) because of the unpredictability. But the same process can be used to determine your own risk levels. You get to decide what level of risk you are comfortable with.
If the risk exceeds your level of comfort, seek shelter somewhere else or move your property if possible. If a tree fails and hits you, it will be uncomfortable to say the least. If it hits your property, there is little you can safely do until the storm passes. Don't become a victim.
