Possibly given how wet everything is going to be and how quick the temp is going to drop + wind.

Things are going to ice up quick, and things like overpasses and anything overhead can be an ice hazard. It’s rare for something like this to happen. Especially with this much rain just before.

Wouldn’t be shocked if a lot of bridges are closed for a bit due to quickly freezing surfaces. Train will be more reliable than crossing the GWB.

Oh and they can’t really salt until the last minute since the rain will wash it away. If it were snow that wouldn’t be an issue.

Tomorrow will be interesting. Hope everyone stays safe.

This was really well explained. I didn’t even think about the salting while it’s raining; and the risk of the salt just being washed away if they salt while it’s still raining.

I also don’t know how they plan to salt the roads when the temperature is forecast to drop so quickly in a shorter period of time. I’d guess that they need a lot more widespread salting early on when the temperature drops below 15 F than if it were to drop below like 30 F.

Yea. I’m not sure what the strategy is. Presumably they’re going to salt the crap out of bridges and places that will freeze first then backtrack on the rest.

I honestly can’t recall last time this scenario played out. It’s normally rain or snow. Rain turning to ice at this scale is uncommon.
