rain rain go away

last evening and in the middle of the night the rain was being driven against the windows in the living room and bedroom. all the windows are louvers that do not seal tight and leave gaps around each pane and at the bottom
SO     depending on the direction of the rain,
the water comes in along the sill, down the wall and along the  floor   

see the space at the bottom of the lowest louver, open space for water

I was up half the night mopping up water so I devised a system that slowed done that came in, not smart looking or stylish but serve the purpose

I tucked a plastic bag under the bottom louver and so the water came down the louvers and out on the plastic rather than come in. 

clothes pin fastened the top of the plastic on an upper louver, it looks loose in the pic but when the louvers are closed it tightens up. 

so the plan is to install a plastic strip along the inside of the bottom sill and calk the edge so the water does not come in, barrier so to speak, here's hoping I can find the stuff and then have it work
