No. That air/smoke was blown out of state and out over the ocean nearly a week ago when the powerful front with strong surface winds blew through the state last Thursday night into Friday. Today's rain event is Gulf moisture from the south. There is absolutely nothing to worry about. The only detrimental effect could be runoff from the derailment site itself and percolation into groundwater (they literally buried the "burn pit" to repair the track so they could restore east-west rail service as soon as possible, which is fucked because it wasn't properly cleaned. Because, capitalism.)
