We demonstrate that high accuracy ZTD can be provided even in real-time. Using a state-of-the-art processing strategy we estimate ZTD and horizontal gradients for 162 permanent stations in Europe over 100 days in 2019, covering the event of hurricane Lorenzo. The accuracy of real-time ZTD with respect to the final ZTD product varies from 3.3 to 10.4 mm. The accuracy of real-time ZTD with respect to the ICON numerical weather prediction model varies from 4 mm to 18 mm and we notice station-specific biases, reaching up to ±10 mm. We demonstrate that horizontal gradients show signatures under the severe weather during hurricane Lorenzo in 2019.
