Because of their bowl-shaped design, wind causes problems with umbrellas, particularly during rain storms. The wind can drive rain under the umbrella, causing the user to become wet. Wind can also blow under the dome of the umbrella, which makes holding the umbrella difficult. Strong winds can rip the umbrella from a person's grip. Wind can also create enough upward pressure to tear the fabric loose from the frame or destroy the ribs and mechanism, rendering the umbrella useless.
Innovations have led to development of the compact umbrella, whose main shaft telescopes to a smaller size. Release mechanisms extend the umbrella to its full size and automatically open it with the push of a button. Accidental pressure on the mechanism can cause it to open unintentionally. If carried in a large pocket or purse, or in a crowded area, the premature opening can result in the destruction of the umbrella, a ripped pocket, damage to a purse or injury to other people.
When users close the umbrella inside a dry area, the rain runs off the surface of the fabric. This can create a puddle where others may walk and slip. On carpet, the moisture can soak into the fabric and cause a stain.
Rain at outdoor events can be frustrating, and may tempt you to bring an umbrella. But using one at a spectator event can block others' views. Because of their size and configuration, just one umbrella can effectively block the view of several observers. The umbrella user can sometimes face a choice of either staying dry or having angry spectators behind her.
