Key messages for Gonzalo can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC, and on the web a www.hurricanes.gov/text/MIATCDAT2.shtml.

WIND: Tropical storm conditions are expected within portions of the Tropical Storm Warning area today.

RAINFALL: Gonzalo is expected to produce total rain accumulations of 2 to 4 inches over Trinidad and Tobago and far northeastern Venezuela. Gonzalo is also expected to produce 1 to 3 inches over the southern Windward Islands, the Leeward Antilles, and the remainder of far northern Venezuela. This includes Saint Vincent and the Grenadines, Grenada, Aruba, Bonaire, and Curacao. Isolated maximum amounts of 6 inches are possible in the mountainous terrain of Trinidad and Tobago and far northeastern Venezuela, which may lead to flash flooding.

At 1100 AM AST (1500 UTC), the center of Tropical Storm Gonzalo was located near latitude 10.5 North, longitude 60.5 West. Gonzalo is moving toward the west near 18 mph (30 km/h). A general westward to westnorthwestward motion is expected today and tonight. On the forecast track, Gonzalo will move across the southern Windward Islands this afternoon or evening and over the southeastern Caribbean Sea on Sunday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is forecast before Gonzalo reaches the southern Windward Islands later today. Weakening is expected after Gonzalo moves over the southeastern Caribbean Sea, and the system is forecast to dissipate by Sunday night.

Tropicalstormforce winds extend outward up to 25 miles (35 km) from the center.

The estimated minimum central pressure is 1009 mb (29.80 inches).

Gonzalo is looking very ragged, with a cloud field that more resembles a tropical squall than a tropical storm. If Gonzalo still has a well-defined center, it is located to the east of the primary area of deep convection and is obscured by cirrus clouds. It is possible that ASCAT data will provide more information on the status of Gonzalo later this morning. For now, the intensity is held at 35 kt based on overnight reconnaissance data, but it is possible that Gonzalo is no longer producing winds of that magnitude except in squalls not directly related to the system's circulation.

Gonzalo appears to have continued westward since the last advisory, with a somewhat uncertain forward speed estimate of 16 kt. As noted in the previous advisory, Gonzalo is not expected to gain much latitude today and should continue generally westward for the next day or so. Close proximity to land and unfavorable large-scale environmental factors should cause Gonzalo to weaken and open into a trough by late Sunday, if not sooner. No significant changes were made to the NHC track or intensity forecasts which both remain near the multi-model consensus.
