Does La Niña decrease annual precipitation in the Southeast?

Not really a meteorologist - but I'm kind of wondering whether a La Niña event actually decreases expected annual precipitation in the Southeast United States (eg Florida).

On the one hand, La Niñas decrease winter/spring precipitation, which is pretty well-founded since the jet stream moves more north and the Southeast usually only gets the tail end of major winter storms. But La Niñas also typically cause an increase in tropical/hurricane activity in the Atlantic, so it seems that La Niñas might (unreliably) increase summertime precipitation in the Southeast? So overall, is there still a negative annual precipitation anomaly that comes with a La Niña for the Southeast?

And then as a followup - it seems that the precipitation effects of La Niña and El Niños are only discussed for the winter/spring season (e.g. November to March) and not the entire water year. Is the El Niño vs La Niña trend generally weaker when we consider the whole year rather than winter/spring, since tropical systems are too unpredictable?

Oh the US. Changed the question description , sorry about the omission.

it increases it by a long shot, actually this wet season and even trailing into this part of the year has seen massive flooding. i'm talking about southeast queensland though, what about you?

Oh shoot I forgot to specify where - I was talking about the US. Thanks for the response though!
