Global Flood Detection System - Version 2

An experimental system to detect and map in near-real time major river floods based on daily passive microwave satellite observations. The purpose is to identify and measure floods with potential humanitarian consequences after they occur.

Flood status report for GEOSUR Jamaica


Status: Orange. Current satellite observations show 3 out of 20 areas (15%) having critically high flood magnitude.

The GEOSUR Jamaica monitoring region consists of 20 areas that are analyzed daily, including the following rivers: .

This report does not provide early warning or forecasting information, but describes the current flood status of rivers based on the past 24h of satellite observations.

The status is determined by the number of areas with high flood magnitude (see below), as determined by the Global Flood Detection System based on passive microwave satellite observations of surface water. The status is set to "Red" if more than 10 areas or more than 30% of areas have high flood magnitude. The status is set to "Orange" if more than 5 or more than 10% of areas have high flood magnitude. Otherwise, the status is set to "Green".

Current Status of monitoring areas

Legend: green = no flood, orange = magnitude > 2 (small potential flood), red = magnitude > 4 (potential flood with high return period)

Current surface water and potential flooded areas

Legend: Current surface water detected by satellite (source: JRC): blue signal scale = presence of water, yellow/red magnitude scale = unusual presence of water, indicating potential floods.

Current Rainfall

Legend: Current rainfall detected by satellite (Source: NASA): areas of extreme rainfall (>50mm/day).

Status of all sites

The table below shows the flood magnitude in the past 16 days for all sites in this monitoring region.

Notes: X = No Data (or data being calculated). The data values of today can change if new data is acquired by the satellite.
Table legend: blue shades indicate flood magnitude (mouse over the box to see the value); magnitudes greater than 2 have an orange outline, magnitudes greater than 4 have a red outline.
