Is Juliet a “Rain Puddle” per se?





??

Another feature propagates that isn’t seen on subsurface sensors




M arion
Marion

(Jim’s favorite)

Not seen on radar




Nate

Strongly stratified at the base



Oscar

Is Oscar a puddle?




Paula
Paula

Superheated

Head? Entrainment of warm water from above?






Shera
Shera

Double sided? Succession of several patches?






Yankee1
Yankee

Strongly stratified within the puddle
