Change the println's to print, and I think that'll sort it. (in here)

switch (range) {
case 0:

lcd.setCursor(0,3);

lcd.println("flood");
break;
case 1: // Sensor getting wet

lcd.setCursor(0,3);

lcd.println("Rain Warning");
break;
case 2: // Sensor dry - To shut this up delete the " Serial.println("Not Raining"); " below.

lcd.setCursor(0,3);

lcd.println("Not raining");
break;
}
delay(1); // delay between reads

I'll wager those bogus symbols are a linefeed sequence.

Do you have a 3.3V BMP180 and a 5V I2C LCD display on the same I2C bus ? how ?
