At 1100 AM AST (1500 UTC), the center of Tropical Storm Julian was located near latitude 35.1 North, longitude 46.8 West. Julian is moving toward the northeast near 17 mph (28 km/h). A faster motion toward the northeast and then north over the north Atlantic is expected through Tuesday. Satellite derived wind data indicate that maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Some additional strengthening is anticipated through tonight. Weakening should begin on Monday, with Julian likely becoming post tropical by Monday evening. Tropical storm force winds extend outward up to 90 miles (150 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches).

The system has become better organized this morning, with the low-level center located on the southwestern edge of a persistent mass of deep convection. A 1246 UTC ASCAT-B pass revealed an area of winds over 40 kt southeast of the center, so the system is upgraded to Tropical Storm Julian with maximum winds of 45 kt.
Julian is accelerating toward the northeast (045/15 kt) in the flow to the south of a deep-layer area of low pressure located just east of Newfoundland. The storm is expected to move around the southeastern and eastern periphery of this large low during the next few days, accelerating further and turning toward the north by 48 hours. The track models are all in good agreement on this scenario, and the NHC track forecast is very close to the TVCA and HCCA consensus aids. This new forecast is also relatively unchanged from the previous advisory.
Winds in the storm have increased faster than expected, even in the face of 20 kt of west-southwesterly shear. This shear is forecast to increase substantially in the coming days, with SHIPS diagnostics indicating it may reach magnitudes of 40-50 kt. However, the storm will still be moving over marginally warm waters around 26 degrees Celsius, and its fast motion and some baroclinic forcing could allow for additional strengthening during the next 12-24 hours. Nearly all the intensity models support some strengthening, and the NHC official forecast peaks the winds at 55 kt in 24 hours, roughly between the IVCN and HCCA solutions. Phase-space diagrams suggest that Julian will probably already be going through extratropical transition at that time, and it should be fully extratropical by 36 hours. Gradual weakening is anticipated after 24 hours, and the extratropical low is likely to dissipate over the north Atlantic by day 3.
