High pressure building to the north will provide cooler temperatures and low humidity this weekend, giving us a true taste of fall. Expect plenty of sun with highs in the low 80s and lows dropping to near 60. Breezes will be brisk at times, especially along the coast.
On the coast:
The combination of astronomical high tides due to the recent full moon and increasing breezes out of the northeast this weekend will lead to some heavy surf and possible beach erosion as well as an enhanced risk of riptides. There is also a good chance of shallow coastal flooding around the morning high tides Saturday (10:31 a.m., 8.9 feet) and Sunday (11:26 a.m., 8.7 feet).
Tropics:
"Lorenzo" moved onshore in Mexico Friday morning as a category one hurricane. The system will dissipate over Mexico, but continue to produce flooding rains there as it does.
"Karen" is barely hanging on as a tropical storm in the central Atlantic. Unfavorable winds aloft are hurting this system, which is expected to weaken to a tropical depression this weekend as it moves northwest.
Finally, a new tropical depression has formed in the far eastern Atlantic. This system could become a tropical storm (Melissa) this weekend.
