Short-term operational prediction of flash floods is different from that of large river floods in several aspects (Table 1). Notably, short lead times for forecast, warning and response make operational flash flood prediction challenging, while they also make it a hydrometeorological problem (rather than a purely hydrological prediction problem).
The Flooded Locations And Simulated Hydrographs Project (FLASH) was launched in early 2012 to improve the accuracy and timing of flash flood warnings. FLASH uses forecast models, geographic information, and real-time high-resolution, accurate rainfall observations from the NMQ/Q2 project to produce flash flood forecasts at 1-km/5-min resolution.
Forecasters warn that a slug of tropical moisture in the western Pacific Ocean will bring additional rounds of downpours to an already flood-battered Philippines through Sunday. "A pair of ...
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Filipino: Pangasiwaan ng Pilipinas sa Serbisyong Atmosperiko, Heopisiko at Astronomiko, [4] abbreviated as PAGASA, which means "hope" as in the Tagalog word pag-asa) is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated to provide protection against natural calamities ...
A flood warning is closely linked to the task of flood forecasting.The distinction between the two is that the outcome of flood forecasting is a set of forecast time-profiles of channel flows or river levels at various locations, while "flood warning" is the task of making use of these forecasts to make decisions about whether warnings of floods should be issued to the general public or ...
Flood forecasting is the process of predicting the occurrence, magnitude, timing, and duration of floods in a specific area, often by analysing various hydrological, meteorological, and environmental factors. The primary goal of flood forecasting is to deliver timely and accurate information to decision-makers, empowering them to take ...
On April 24, 2011, the National Weather Service Weather Forecast Office in Memphis, Tennessee, issued the first PDS flash flood watch to highlight the threat for widespread, significant and potentially life-threatening flash flooding due to repeated rounds of severe thunderstorms.
