The Met Office has issued two yellow weather warnings for heavy rain and gusty winds across Northern Ireland.
A heavy rain warning will be in place from 6am on Friday to 9pm later that night - and they say it is "likely to lead to some travel disruption".
They are warning of potential flooding of homes and businesses; bus and train services could be affected with journey times taking longer and spray and flooding on roads, which is likely to make journeys longer.
And on Saturday, a second yellow warning is in place - but this time for "strong gusty winds".
The Met Office said: "Strong gusty winds in association with showers may bring some travel disruption.
"Some delays to road, rail, air and ferry transport are likely. Probably some bus and train services affected, with some journeys taking longer [and] delays for high-sided vehicles on exposed routes and bridges likely.
"Some short term loss of power and other services is possible [and] it’s likely that some coastal routes, sea fronts and coastal communities affected by spray and/or large waves."
