st: Dealing with an unusual peak in time-series data

Hi all,
I have data on monthly counts of certain events for about 20-year period.
I looked at the temporal pattern of the monthly counts, and I found a HUGE peak in the middle of the data (for 2-3 months).
I wonder whether or not it is ok to estimate a time-series model like negative binomial regression (this data has lots of zeros) when the data looks like this. Any other model suggestion?
I will greatly appreciate your feedback.
Thanks.
