Summary
EFAS v4.4 introduces minor changes to the system, as well as some general bug fixes. Here is a summary of the main changes:
...
- The graphs which appear when an ERIC Flash Flood Reporting Point is clicked on the EFAS website have been updated so that 1) a vertical dashed line is now shown at 48 hours lead time, and 2) dashed lines are displayed for the 30th and 70th percentiles rather than the 25th and 75th percentiles.
- These changes mean the visualisation of this layer will now be consistent with the criteria used for issuing flash flood notifications, as 48 hours is the maximum lead time for issuing a flash flood notification and the 30th percentile is used to identify when the 5-year return period is exceeded.
