Narrative:

We were taxiing out from gate for takeoff when a severe storm began at the airport. We had only taxied a short distance from the gate and were stopped along the grass line of the ramp to await our edct; on what used to be called taxiway J. The storm was so severe the control tower could not see us from the tower cab and since we were going to wait until the storm passed before continuing; ground control asked us our position. I replied that we were on taxiway J. However; the airport diagram (10-9 page) no longer accurately depicts the taxiway configuration around the ramp area; as a result of additional taxiway concrete being laid outside the existing ramp in preparation for the construction of a replacement terminal B in the future. As a result; the taxiway identifications no longer match the printed guidance available in the flight deck. This caused temporary confusion as ground control thought we had entered the new taxiway instead of staying on the ramp. They asked us for clarification; and we told them we had remained on the ramp; on what used to be called taxiway J; the portion of the main ramp along its western edge between where taxiway right hits the main ramp and taxiway J appears to hit the main ramp on the 10-9 page (dated 4 jan 13).for some reason; [commercial charting company] has not issued an update to its taxi diagram for jax since the new taxiways have been opened (at least four months ago). In addition; jax does not have access to modern taxiway monitoring tools such as asde-X. As a result; tower controllers must rely on the ability to see aircraft positions on the airport; or ask the aircraft for position reports in the event of fog or heavy rain. Aircraft have difficulty describing their location due to the airport diagram not matching the current actual taxiway configuration.I suggest updating the airport diagram to reflect the current actual taxiway configuration. In addition the airport might consider installing asde-X in the control tower.

Title: An A320 First Officer advised the commercially provided airport page for JAX does not illustrate the revised taxiways not in use. Subsequent to this report a new page was published with the revised taxiways illustrated.
