More typical late spring weather is expected to return over the weekend.

The National Hurricane Center is issuing advisories on Tropical Depression One, located over the western Atlantic Ocean off the east-central coast of Florida.

Information on Tropical Storm Arthur



Tropical Storm Arthur Discussion Number 11
NWS National Hurricane Center Miami FL AL012020
500 AM EDT Tue May 19 2020

Arthur's cloud pattern has continued to take on a generally post-tropical appearance, though a recent convective burst near its center suggests that it isn't quite post-tropical yet. Satellite imagery and earlier scatterometer data also indicate the presence of a developing warm front near the cyclone's center, and this could be contributing the the development of the aforementioned convective burst. ASCAT-C data that arrived early this morning showed maximum winds of 45-50 kt, and this was the primary basis for the initial intensity.

Virtually no change was made to the intensity forecast. Despite the recent increase of convection near Arthur's center, extratropical transition should finish fairly soon. Slight strengthening due to baroclinic forcing is possible through the afternoon, but the cyclone is forecast to begin spinning down by tonight or Wednesday morning. The global and regional models indicate that the system will dissipate within about 72 h, and this is reflected in the official forecast.

Only small adjustments were made to the track forecast, which remains near the multi-model consensus. As Arthur weakens it should be steered generally southward around the east side of a low-level ridge. The models differ on how quickly the southward turn will occur, but all agree on that general scenario. The latest NHC forecast is a little west of the previous one after 24 h.

Dangerous coastal surf conditions and rip currents are expected to continue along portions of the mid-Atlantic and southeast U.S. coasts during the next couple of days. See products from your local National Weather Service Forecast Office for more details.
