Please direct me to the full bulletin where this came from. I'm going to use this elsewhere but I want to site where it came from. thanks!!

Hurricane Maria Discussion Number 18 NWS National Hurricane Center Miami FL AL152017 1100 AM AST Wed Sep 20 2017 The last radar image from the San Juan WSR-88D was received at 0950 UTC when Maria's eye was located only about 5 n mi off the southeastern coast of Puerto Rico. Subsequent 1-minute imagery from the GOES-16 satellite, as well as surface observations, indicate that the eye made landfall a little south of Yabucoa Harbor, Puerto Rico, around 1015 UTC. Now that the center is moving over the mountainous terrain of the island, the eye has become cloud filled, and the infrared satellite presentation has degraded. Without radar velocity data, the initial intensity is incredibly uncertain, but my best guess is 120 kt based on a typical inland decay rate. Maria's center is expected to move off the northern coast of Puerto Rico soon, and an Air Force Reserve reconnaissance aircraft is scheduled to intercept the center early this afternoon and provide a better estimate of how much Maria has weakened. The initial motion is northwestward, or 305/10 kt. This northwestward motion is forecast to continue for the next 48 hours, followed by a turn toward the north by days 4 and 5, while Maria moves between a mid-level high centered southeast of Bermuda and a broad trough extending from Tropical Storm Jose southwestward into the Gulf of Mexico. The track guidance is tightly clustered this cycle, and there were no significant changes made to the NHC forecast track. Once Maria moves off the coast of Puerto Rico, it will take some time for the structure to reorganize over the warm waters of the Atlantic Ocean. However, the shear is expected to be less than 10 kt for the next 24-36 hours, and Maria has an opportunity to restrengthen a bit over that time period. After 36 hours, a gradual increase in shear is likely to lead to a commensurate gradual decrease in the hurricane's intensity through the end of the forecast period. Since the SHIPS model, in particular, responds to the favorable conditions for intensification, the NHC intensity forecast lies just above the intensity consensus through much of the forecast period. Since we don't have radar imagery from San Juan, and the eye has become cloud filled in satellite imagery, the hourly position updates are being discontinued. KEY MESSAGES: 1. Maria's core is moving over Puerto Rico, with life-threatening wind, storm surge, and rainfall impacts continuing over the island. Everyone in Puerto Rico should follow advice from local officials to avoid life-threatening flooding from storm surge and rainfall. A Hurricane Warning remains in effect for the Virgin Islands, but conditions should gradually improve there later today. 2. Wind speeds atop and on the windward sides of hills and mountains and on high-rise buildings could be much stronger than the near-surface winds indicated in this advisory. 3. A Hurricane Warning is also in effect for the northern coast of the Dominican Republic, the Turks and Caicos Islands and the southeastern Bahamas, where Maria is expected to bring dangerous wind, storm surge, and heavy rainfall.

Apologies if repeat... two pages per hour makes it hard to keep up while at work. Video from St Croix, USVI this morning. Damaged, not destroyed. eye passed about 10 mi to the SW. https://twitter.com/BillKarins/status/910480473562009607

As we watch the developments, I want to mention that many of us have family (US Citizens) who live in the USVI. They are as much of a concern as a mainland landfall. I know there are many weenies who are cheering every hurricane on to be bigger and stronger. I'm ok with an epically strong fish storm.... or if it took a substantial southerly jog for the evening then I may be ok with an epic build before a hard right around the ridge... As far as those Americans on St Thomas and Croix, etc, Maria is tomorrow. drops $0.02.

I still respectfully stand behind my original comment. Compare technology in 1951 to that of 2017. The tools are different now. Satellites can read your newspaper through the living room window. We have much more accuracy now. still within average. If we start having more and more years where we run out of alphabet names, we can start discussing above avg totals.

Sounds like it's within avg to me.
