Tomorrow, September 10th, is the statistical peak of the hurricane season and the Atlantic basin is showing signs of increasing tropical activity.

Tropical Storm Gabrielle just made landfall at Cape Lookout, North Carolina, and a more northeastward movement is anticipated this evening. Gabrielle is still encountering some north to northeasterly shear which should keep the maximum surface winds offshore as she merges with an extratropical low off southeast New England on Wednesday or Thursday.

Upper level low in the Bahamas, with a surface reflection near 27.4N 77.1W at 09/14Z, is drifting slowly to the northwest under southerly wind shear. Additional development is not anticipated, however showers and squalls are likely over the Florida peninsula today, tonight and on Monday.

Invest 90L in the east central Gulf of Mexico near 23N 87W at 09/14Z is currently stationary and quite disorganized with easterly shear to the immediate north of the system. Given the rather hostile environment, development is not expected.

Invest 91L in the far eastern Atlantic near 10N 34W at 09/14Z is moving west at 10 knots and slowly becoming better organized. Additional development seems likely with movement to the west but becoming west northwest in a couple of days as the system continues to consolidate. Slow movement westward at about 10-12 knots into an area of lighter wind shear.

Finally, recently designated Invest 92L near 17.3N 57.5W at 09/14Z has become much better organized in the past 24 hours. Movement is to the west at 12 knots. This system will be moving away from a zone of westerly shear into an area of almost no wind shear. A west northwest track is anticipated. Additional development is quite likely and residents of the Bahamas and the southeastern U.S. should closely monitor the development of this potentially troublesome system.

Lots of areas to keep an eye on as the hurricane season hits its peak.
