FsShelter 
FsShelter is a library for defining and running Apache Storm topologies in F# using statically typed streams.
It is a complete rewrite of FsStorm with the goals of static typing, modularity, and pluggable serialization. It comes bundled with Json serialization and Protobuf (Protobuf requires corresponding Storm multilang serializer implementation Protoshell).
See docs for for an intro and an overview.
