Single word for “to start earlier”

I’m looking for a word that indicates that a time interval will start earlier than previously expected. When it’s “to prolong”, because that’s something that can happen to the same interval (and “prolongation” is already used in that context).

Why

  you're "last -> longer" -> "prolongation" -> "start earlier" -> "?  

Almost

all the major airlines are sending severe weather warnings to customers, mostly a few hours in advance. Sometimes it happens that severe weather lasts longer than expected. We call that a “prolongation” internally. In this case we may send “prolongation warnings.”

Similarly, it can happen that extreme weather starts earlier than expected. Does an event have a longer duration, which can cause its end sooner, or it could even be the duration is even longer? I have started calling this an “earlification”, which transports the meaning, but is a little lacking in elegance.

In general, these words are used in internal, informal documentation and source code. Generally, computers and databases are not used at

all in business communication.

For severe weather starting earlier: hastening.

Why if MW causes things to happen more quickly.

Is there something else that has occurred faster?

You may consider prematurely

: happening too soon or earlier than usual : happening, arriving, existing, or performed before the proper, usual, or intended time. I

like the

word over-early because it is fun, but I don’t think people use it much other than prose.
