When you consider that we joke about weathermen (What other job can you get it wrong every day and still have a job tomorrow>), these guys did pretty well.
My dad was a meteorologist for the Navy in WW2 and later for his entire career with the US Weather Service.
He heard all the jokes over the years and told me once "Son, don't ever say 100% chance of rain, make it 90% chance because someone, somewhere will get no rain and think you incompetent. Same goes in reverse for 0% chance of rain."
Ask any sailor and they will tell you how difficult it is to predict the weather, even when their lives depended upon it.
One never gets it right all the time.
Oh BTW, when he retired my dad bought a lakehouse that he scouted out that was in a 100 year flood zone. After he passed, the house got under water twice. Even the best can err.
