I have to admit, I have yet to use this umbrella during a heavy rain storm with heavy winds, but from the times I have used it, it seemed sturdy and it did not budge during mild winds. Not only is it sturdy, but it is a nice looking umbrella as well. The wooden handle is smooth and the London Fog logo is a nice touch. The auto open functions smoothly and quietly and there are no difficulties getting it to close. It is not auto close, but that doesn't really take away from the functionality of the umbrella. The velco strap that wraps around the umbrella also displays the London Fog logo, which is an additional nice touch. I do not believe I will have any problems with this umbrella during a heavy storm. It seems sturdy and it certainly has weight to it, although not too heavy. I highly recommend.
