Looks like much of the country is covered by fairly heavy cloud and areas of rain, scattered in the north and central Belize and heavier in the south. My guess is that significant cloud will continue over most parts of Belize for most of the day, possibly a few glimpses of sun later, but the chance of rain will be around for most of the day in any parts of Belize, more so in the south.
Looks like today will be mainly overcast, just the odd chance of any sunshine, a significant chance of rain.
