Given our extreme weather this week — with storms and king tide washing water into South Florida streets — it could have been worse for partygoers and trick-or-treaters.

But Halloween will be a mixed bag. King tides may be ebbing, but rain will be increasing.

“The Halloween forecast is not looking too scary,” said Lissette Gonzalez, a meteorologist with Miami Herald news partner CBS News Miami.

Gonzalez said there’s a “potential” for rain, with showers blowing in around trick-or-treating time between 5 and 7 p.m.
