Tropical Storm Bonnie - Miami Beach, Florida - July 23, 2010

On July 23rd, 2010 Tropical Storm Bonnie became the second named, and second landfalling, storm of the 2010 Atlantic hurricane season.

Between July 20th and 21st an area of disturbed weather associated with a tropical wave, interacting with a large upper-level low, moved west-northwest over the northeastern Caribbean and southeast Bahamas producing very heavy rainfall and extensive flooding over Puerto Rico and the Dominican Republic. On July 22nd, the strong shear, that had been preventing development, relaxed as the upper-low moved far enough west of the disturbance. By morning, visible satellite imagery indicated that a low-level center had formed over the central Bahamas and by 11am, the system was classified Tropical Depression Three, while moving west-northwest towards Southeast Florida.

By early evening on the 22nd, the depression reached Tropical Storm strength and was named Bonnie. In response to strong southeasterly winds on the east side of the upper-low, Bonnie moved more towards the northwest before bending back towards the west-northwest on the morning of the 23rd. These strong upper-level winds also prevented strengthening and Bonnie struggled to maintain deep convection near the center while remaining a weak tropical storm as it rapidly approached southeast Florida.

Between 9am and 11am on July 23rd, the center of Tropical Storm Bonnie moved rapidly west-northwest at 18 mph (16 kts) across Biscayne Bay, making landfall near Cutler Bay, Florida (just south of Miami) as a minimal tropical storm with maximum sustained winds of 40 mph (35 kts) and a minimum central pressure of 1008 mb (29.77 in). One large primary rainband to the northwest and west of the storm's center brought some brief heavy squalls to the coastal areas of Miami-Dade county as Bonnie neared landfall.

On the morning of July 23rd, storm chaser Michael Laca intercepted Tropical Storm Bonnie at Miami Beach, Florida. At my location I encountered a brief period of sustained winds near 35-40 mph (30-35 kts) with peak gusts near 45 mph (40 kts) and heavy rain.

Tropical Storm Bonnie had a very small wind field and produced a brief period of minimal tropical storm condtions across portions of Miami-Dade county. The highest officially reported winds in southeast Florida during Bonnie's passage were 47 mph (41 kts) with a peak gust of 58 mph (50 kts) at RSMAS on Virginia Key (just south of Miami); 31 mph (27 kts) with a peak gust of 39 mph (34 kts) at Tamiami airport and 26 mph (23 kts) with a peak gust of 36 mph (31 kts) and a minimum pressure of 1009.4 mb (29.81 in) at Homestead General Airport in extreme southern Miami-Dade county. Unofficial wind readings include 41 mph (36 kts) with a peak gust of 47 mph (41 kts) from a private anemometer in the community of Palmetto Bay, along with a minimum pressure of 1007 mb (29.74 in).

During the late morning and afternoon, Tropical Storm Bonnie exited the southeast metro areas and crossed the southern Florida peninsula, emerging into the Gulf of Mexico as a tropical depression by early evening.

Due to the continued proximity of the large upper-level low to the west of Bonnie, strong southeasterly shear prevented the depression from restrengthening and Bonnie degenerated into a low-level remnant swirl over the northern Gulf of Mexico on July 24th. The remnant low eventually crossed directly over the BP oil spill area and made landfall over southeastern Louisiana with little effects.

o.o bonnie looks more deadly in this video than it really was

[vmax135]

@wiiluigi1998 Yeah, Bonnie was definitely a less than impressive event... there was a brief period of stronger winds associated with the primary band on the northwest side of the center but, other than that, it was really a non-event.

[MrShanfara]

nice video man and nice weather to me !! its so hot here and no rain at all

[vmax135]

@MrShanfara Thanks so much! There really wasn't that much rainfall associated with Bonnie, all the significant weather occurred with the one primary rainband shown in this clip.

When I was in N.C. we had one named Bonnie come thru, it wasn't strong or very damaging so the name wasn't retired from the lists. I can't remember, but I think there is a limit on how many times a certain name can be used. Seems like I remember 3 or 4 storms that had my name. The strongest one being a Cat 4 that never made land fall in the same year Andrew hit Florida which I believe was 1992. It was Hurricane Chris, which took that NE swing out into the Atlantic.

@Torn80cj Yeah, Bonnie in 1998 (the one that went into NC) was probably the most impressive of all of the "Bonnies" we've had through the years. I think it's technically the strongest, peaking at 115mph (Bonnie in '92 peaked at 110mph). Unfortunately there isn't any limit on how many times a name can be reused, so they'll keep using Bonnie every six years until it's a significant enough storm to be retired. 2010 was the sixth time the name has been used since it was first introduced in 1980.

Where I live in Boca, it wasn't really a big deal at all. We just had a brief period of fairly gusty winds probably in the 30-35 MPH range but I didn't really see any noteable damage--maybe just loose objects and leaves. There were some very minor street flooding but just as bad as any ordinary summer thunderstorm.

[javalvo1]

I was in Boca Raton and nothing happened...

[TheTornadoF1]

You got some pretty good footage of that storm hurricane ike category two hit us when i lived in houston

[HURRICANEM5]

I didn't even know about this tropical storm o.O That was last summer and I had NO idea we were under this storm xDDD I think I was at my cousin's house on that day actually. Cause her birthday is the 22nd of July but I remember we had to celebrate it the day after. Wow. Was it at all noticilble in Kendall? Cause that's where I live. ..
