submerge

My usual morning walk with Milo started like every other morning, except this morning by the time we had reached the Marina a blanket of mist was rolling in from the ocean and submerged the whole of Mindarie and beyond.

Usually i can see the next suburb of Quinn's rock, one minute there were blue skies where I could see for miles the next we were almost engulfed, submerged into darkness, it was very eerie, within an hour or so it had completely disappeared.
The cloud coverage was excellent timing for the topic today, it was just a pity it didn't submerge us long enough!
