Ua is rain. Hawaiian has dozens of names for particular rains, each tied to a place: the Kanilehua of Hilo, the Tuahine of Mānoa, the Līlīlehua of Pālolo. Rain is a blessing and a sign of a place's fertility, so it is welcome in names: Ualani is heavenly rain, Kaua the rain, Leiua a lei of rain.
Say it OO-ah. Every vowel is pronounced, and the capitalized syllable takes the stress. The pronunciation guide covers the rules.
