There’s a weather system off Georgia with an 80 percent chance of turning into a named storm and then possibly into Hurricane Arthur. And that could make for a wet, stormy Fourth of July in Boston.

And while we’re still several days out, if you’re planning on joining the hordes on the Esplanade, keep a close eye on the forecasts the rest of the week.

If you use Twitter, consider following meteorologist David Epstein, who covers weather for boston.com. On Tuesday morning, he said concerns over a stormy Fourth may be overblown.

In JP itself, a series of stormy afternoon/evenings starting Wednesday could impact the First Thursday Art Walk, which runs from 5-9 p.m. on Thursday. Rain could be a problem for Screen on the Green, an outdoor movie night at the Loring-Greenough House. This week’s movie, set to screen around 8 p.m. Thursday, weather permitting, is The Little Mermaid.
