ELI5: How are weather balloons deployed so that they do not pose a risk to commercial air traffic?

Given the fact that weather balloons are frequently deployed to obtain critical measurements for making more accurate weather forecasts, how do pertinent governmental agencies ensure that they do not pose a risk to commercial air traffic where there is a likelihood that a collision/impact with these balloons may take place?

There is a suggestion that the local air traffic controllers be notified of the intended launch of a high altitude balloon so its presence is known, but the more relevant regulations regard the content of the payload. There are limits on the total weight and density of the payload, as well as the separation force of the payload from the balloon. The intent of those regulations is that on the exceedingly low chance that such a balloon would be struck by an aircraft it wouldn't cause any significant damage.

Remember that the sky is very large and there aren't really that many aircraft in flight. Hitting a weather balloon by accident is just an incredibly remote chance; far more likely is hitting a bird of which there are quite a few. If the payload is roughly the size and weight of a crow then a commercial jet engine would deal with it in much the same way it would the crow, namely going "Nom nom nom!" and not really caring.
