According to a statement released by NOAA on April, 9 2021, the Atlantic hurricane season averages have changed.
“Beginning with this year’s hurricane season outlooks, NOAA’s Climate Prediction Center (CPC) will use 1991-2020 as the new 30-year period of record. The updated averages for the Atlantic hurricane season have increased with 14 named storms and 7 hurricanes. The average for major hurricanes (Category 3, 4 or 5) remains unchanged at 3. The previous Atlantic storm averages, based on the period from 1981 to 2010, were 12 named storms, 6 hurricanes, and 3 major hurricanes.”
CERA visualizes time series for water levels, wind, and significant wave height for any location on the map. To use this feature, click on the time series button on the left of the map, then click on the desired location on the map.
CERA’s 2021 release now allows downloading the selected time series as a .json file. The download link is in the top right of the time series chart.
If finding a time series for a specific coordinate point is desired, click on the time series button, then click on the location search button on the left of the map. If you already have a chart open, the coordinate pair is pre-filled in the search box. If you would like to find another place, enter the coordinate as [latitude, longitude]. CERA will open the time series chart automatically.
What is the Compound Flood Inundation Guidance System (CFIGS)? CFIGS is a compound flood prediction system developed at CE Hydro, capable of predicting flooding due to the combined influences of precipitation and storm surge/tidal fluctuations. It provides flood inundation guidance to promote understanding of the timing and extent of flooding before the event.
With CERA’s headquarters at the Louisiana State University (LSU), the team is excited to include this local and unique model prototype on immediate display for users to view and operate. View it here on CERA.
CFIGS was made possible with the support from Coastal Protection Restoration Authority (CPRA), Louisiana SeaGrant, Louisiana State University (LSU), Seahorse Coastal Consulting and Freese and Nichols, Inc (FNI).
We have been working with the NOAA Coast Survey Group to retrieve the ESTOFS-Global maximum wind levels from their cloud service and are happy to announce that the GFS forced wind maps are now available on the CERA web mapping tool.
The CERA team is happy to announce a major upgrade using the Global Extratropical Surge & Tide Operational Forecast System (ESTOFS-Global) developed by NOAA’s Office of Coast Survey. High-resolution water level forecast guidance is now provided for the entire globe.
CERA provides the maximum water level height for the 06Z UTC cycle once a day. Using the CERA ‘time series’ feature displays maximum water levels at any point of interest on the map.
Unregistered users will now see the ESTOFS-Global map by default. Registered users can switch between ESTOFS-Global and customized maps from ADCIRC Surge Guidance System (ASGS) at any time using the ‘Select a model’ box at the top of the site.
You can also use the “Map Settings” option dialog at the upper right of the website to change your model preference upon opening CERA.
With this update, CERA transcends its national capability to an international level in extratropical flood forecasting using NOAA’s data.
The CERA Group is excited to announce a first release for selected hindcasts that will allow you to download the maximum inundation with a 50 meter resolution from the CERA website.
The following hindcasts are now available for download as GeoTIFF:
2020: Zeta, Delta, Sally, Laura, Isaias, Hanna 2019: Dorian, Barry 2018: Michael, Gordon, Florence 2017: Irma, Harvey 2016: Matthew
To download these GeoTIFFs, please select the maximum inundation layer from the legend for the desired storm, then select the download button in the top right (“Download GeoTIFF”). CERA has the capability to create GeoTIFFs on demand. We will provide this functionality for storm runs in the 2021 hurricane season.
