I can understand why power might go out, as from my understanding, that’s usually power lines going down due to tree branches and/ or other breakages somewhere down the ‘line’ (haha). Why would lights flicker though? Wouldn’t that mean that nothing’s breaking between the energy distribution points and the point of observation? If energy can still get from point A to point B, what causes it to lose its intensity, or even cease for a moment, before returning?

it depends on the type of storm, but even strong winds can sway power lines in a certain way that will cause flickers because of temporarily stressed/lost connections
The power grid doesn’t have just an on or off state, the voltage can dip due to the action of protective devices, or when it’s windy it can cause lines to clash, and outages can be momentary due to the fact that the power grid is designed to keep the supply going as much as possible, meaning that when you have a momentary fault on the line such as a clash, the protection devices will make an attempt to re energise the line, if the fault is still there or happens multiple times within a given period the protection devices will enter a locked out state, notifying grid controllers of a permanent fault on that circuit who then get repair crews on the road who then have to inspect every span of line until they locate the fault and get it fixed.
