WPC Rainfall Guidance for Tropical Cyclones

WPC Rainfall Guidance for Tropical Cyclones
  • Describe the unique challenges of tropical cyclone QPF.

  • Explain how the WPC QPF and PQPF are created and how to interpret their output.

    • Differentiate between the way WPC and NHC use probabilities in their products.

  • Identify which products complement deterministic QPF by offering information about forecaster confidence, worst-case scenarios and message highlights.

    • discussion products

    • excessive rainfall outlooks

    • probabilistic QPF

  • Identify three high-resolution tools (other than flash flood guidance) which influence the WPC Excessive Rainfall Outlooks.

  • Use WPC QPF, PQPF, and Excessive Rainfall Outlook to determine the location, amounts of greatest precipitation, and confidence in these forecast parameters

    • Contact WPC to discuss how to refine the message for the local level
