Local Tropical Cyclone Precipitation Forecasting and Communication

Local Tropical Cyclone Precipitation Forecasting and Communication
  • Explain how TC characteristics (track, intensity, forward speed) and terrain can affect TC precipitation distribution and magnitude.
  • Explain the importance of antecedent conditions when determining TC flood potential.
  • Assess the heavy rain potential and identify the areas most likely to be affected.
    • Determine the potential flooding rain impacts of a TC upon a WFO’s local area of responsibility.
    • Derive an appropriate flash flood and/or river flood message for societal response.
  • Describe situations when a FLASH FLOOD EMERGENCY should be issued.
  • Coordinate/collaborate TC rainfall forecasts with WPC, RFCs, and other WFOs (via NWSChat, phone, etc.).
