頫 is not used independently in modern Chinese. It is an old variant of 俯 (to bow the head, to look down); the calligrapher Zhao Mengfu used it in his courtesy name 子昂. Always write 俯 today.

Classical / variant only - seen in old texts and calligraphy, not in modern Chinese.
Left side 兆 is the sound element, with a strong drift from zhào to fǔ. It carries no 'omen' meaning here. The standard form 俯 uses a different phonetic for the same word.
