I think we need to document the parameters (that is, create a documentation subpage, and transclude it at the template). For example, what in the world are these?:
- |MD|MD=MD
- |extra|EX=EX
- |unknown=?
- |typhoon|TY=TY
- |strong|swiosts|STS=STS
- |sprcyclstorm|SUCS=SUCS
- |esvrcyclstorm|ESCS=ESCS
- |vsvrcyclstorm|VSCS=VSCS
- |svrcyclstorm|SCS=SCS
- |cyclstorm|CS=CS
- |deepdepression|DD=DD
- |niodepression|D=D
- |land|LD=LD
- |low|TL=TL
- |disturbance|swiodisturbance|subdisturbance|DI=DI
- |vintense|VITC=VITC
- |intense|ITC=ITC
- |swiotc|TC=TC
- |mtstorm|sub|MTS=MTS
- |ZODW=ZODW
