July 31, 2017 — Tropical storm "Emily" will have NO direct local impacts on Jacksonville/NE Fl./SE Ga. Onshore winds out of the east are already occurring at our area beaches & may be augmented slightly by "Emily" as the tropical cyclone moves offshore about 155 miles south/southeast of Jacksonville overnight tonight near Melbourne. The onshore flow will result in a heightened rip current risk - never swim or surf alone & stay as close to a lifeguard as possible.
"Emily" moved ashore at 10:45am just south of Tampa Bay on Anna Maria Island just west of Bradenton. Wind gusts between 55 & 60 mph were measured near Tampa Bay.
- Heavy rain will be the primary concern with rainfall of 4-6"+ along & south of I-4
- winds will be a secondary threat with gusts of 40+ mph which could topple some trees especially since the ground is saturated.
- isolated waterspout/brief tornado threat
- little or no storm surge
Beware of stalling fronts during the hurricane season...
& low & behold: tropical storm "Emily" formed over the far Eastern Gulf of Mexico. Some weakening will occur over land before back over the Atlantic by early Tue. The interaction with land & dry air to the immediate north + increasing shear should not allow for much recovery once back over water & "Emily" will stay well to the south & east of Jacksonville.

Imagery below courtesy CIMMS continues shows the African Saharan dust (orange & red) over the Central & Eastern Atlantic. A fairly strong wave has emerged off the coast of Africa & some potential for gradual development during the next week or so as the wave moves into the Central Atlantic.

Surface analysis centered on the tropical Atlantic shows the strong Bermuda high remains anchored over the Central Atlantic...
Surface analysis of the Gulf:
Wind shear analysis (red is stronger shear - still very evident over the Caribbean)... note the strong shear over & near Fl. in the vicinity of "Emily":
In the E. Pacific.... "Irwin" will soon dissipate & the last advisory has been issued on "Hilary" to the north over cooler water. There is some rough surf & a high rip current risk up & down the Baja Peninsula & S. California...
The W. Pacific...... "Noru" continues well to the southeast of Japan....
