I just checked and it seems that HF.15099 is just the event that sets up the weather tombola (random event generator). The actual tombola is HF.15120 and is found in the vent file hf_african_flavor_events.txt
HF.15120 in turn has a random list of 10 items, each with a base chance of 10, but with the last one (no event) remarked out. The base chance for each event is modified by things such as rain dances, current drought etc.
Here is a snippet from the start of the event that details the various outcomes -
Code:

}
