Not...strictly...thinking of having anything like tornadoes.

Maybe there could be a similar, but obviously even more potent and dangerous phenomena that could occur from time to time, where such a haze would envelop and entire region. While our frames would sustain very minimal damage over-time from the constant exposure, it would be far more hazardous to un-shielded pilots. G-suits and past genetic engineering aside, humans could suffer serious effects if they were to be exposed to it, when their frames would get too damage or they would be caught in it, for whatever reason. It could cause a temporary lockdown for larger, more open bases, where outside activity (barring automated construction by basic builder-mechs and piloted omni-frames), would be reduced, as personnel would have to stay indoors. Of course, such periods could present opportunity for the Tsi-Hu and any other factions for an attack on those bases, maybe multiple bases, at the same time. Like, an invasion event.
Also, this could affect our navigation, communication and targeting systems, as well. Reducing sensor ranges, sensor precision (so objectives and enemies would be harder to track as any markers couldn't be placed completely accurately). In more concentrated pockets, it could reduce visibility and make it risky to use certain types of weapons, like, flamethrowers or shock weapons that could backfire and injure our frames and eventually us, if we're not careful.

About three miles (4.8 km) to the east of the plant on the coast, deadly clouds of acid and glass particles billowed into the sky as lava fell into the ocean from two flows blocking Highway 137, one of the main exit routes from the volcano area.
Laze -- a combination of "lava" and "haze" -- is a caustic a caustic mix of hydrochloric acid fumes, steam and fine volcanic glass specks created when erupting lava, which can reach 2,000 degrees Fahrenheit (1,093 degrees Celsius), reacts with sea water.
"If one were to be near the laze, because of the various acids, it would be corrosive to the eyes, the nose and respiratory tract, and the skin," Dr Alvin Bronstein from the Hawaii State Department of Health told journalists on a conference call.
