"JUNE" Tropical Storms (1851-2013):

[ncforecaster89]

Hey everyone,

This particular thread is from a revised and updated blog entry that I have written on WU. In it, we will continue our examination of the entire historical record (1851-present), with a focus on "June" Tropical Cyclone (TC) activity throughout the North Atlantic basin. A "June" TC will be characterized as one that initially developed at some point during the month of June (i.e. June 1-June 30). Those TCs (shown by year) that achieved hurricane (H) and/or "major" hurricane (MH) intensity will be designated by bold case print in the following respective sections.

ALL TROPICAL STORMS:

Note: Those tropical cyclones that achieved hurricane intensity will be identified by bold case print.

3 = 1886 (3 H), 1909 (1 H), 1936 (1 H), and 1968 (2 H).

2 = 1871, 1902 (1 H), 1906 (1 H), 1957 (1 MH), 1959 (1 H), 1982 (1 STS/1 H), 1986 (1 H), 2005, 2012 (1 H), and 2013.

1 = 1851, 1854, 1857, 1858, 1862, 1865, 1867, 1873, 1880, 1887, 1888, 1889, 1892, 1893, 1894, 1899, 1901, 1904, 1907, 1912, 1913, 1921, 1922, 1923, 1924, 1929, 1931, 1933, 1934, 1939, 1945, 1946, 1954, 1956, 1958, 1960, 1964, 1965, 1966 (MH), 1972, 1974 (STS), 1975, 1979, 1981, 1989, 1993, 1995, 1996, 1997 (STS), 1999, 2001, 2003, 2006, 2007, 2010, and 2011

This is a visible satellite image of H Alex (at peak intensity) just before it came ashore along the NE Gulf Coast of MX, on June 30, 2010. It is the most recent June TC, of at least category two hurricane intensity, to develop anywhere within the Atlantic basin.

0 = 1852, 1853, 1855, 1856, 1859, 1860, 1861, 1863, 1864, 1866, 1868, 1869, 1870, 1872, 1874, 1875, 1876, 1877, 1878, 1879, 1881, 1882, 1883, 1884, 1885, 1890, 1891, 1895, 1896, 1897, 1898, 1900, 1903, 1905, 1908, 1910, 1911, 1914, 1915, 1916, 1917, 1918, 1919, 1920, 1925, 1926, 1927, 1928, 1930, 1932, 1935, 1937, 1938, 1940, 1941, 1942, 1943, 1944, 1947, 1948, 1949, 1950, 1951, 1952, 1953, 1955, 1961, 1962, 1963, 1967, 1969, 1970, 1971, 1973, 1976, 1977, 1978, 1980, 1983, 1984, 1985, 1987, 1988, 1990, 1991, 1992, 1994, 1998, 2000, 2002, 2004, 2008, and 2009.

Note: Storm #2 of 1916 (MH), storm #1 of 1994 (TS Alberto), and storm #2 of 1997 (TS Ana) were each a late "June" TC that didn't intensify into a TS until "July".

In addition: Storm #1 1857 (TS), storm #3 1886 (H), storm #2 1933 (H), storm #1 1975 (TS Amy), storm #2 1981 (TS Bret), storm #2 2003 (TS Bill), and storm #1 2010 (H Alex) were each a June TC of either TS or H intensity that at least retained TS intensity into July.

ALL U.S. TROPICAL STORM LANDFALLS:

Note: These totals combine both Tropical Storm and Hurricane landfalls (i.e. all named storms). Hurricanes will be shown in bold case print.

3 = 1886 (3 H).

2 = 1871, 1902, 1906 (1 H), 1909 (1 H), 1936 (1 H), 1957 (1 MH), 1968, and 1982 (1 STS).

1 = 1851, 1854, 1865, 1867, 1873, 1880, 1887, 1888, 1889, 1892, 1893, 1899, 1901, 1907, 1912, 1913, 1921, 1923, 1929, 1931, 1934, 1939, 1945, 1953, 1954, 1956, 1958, 1960, 1965, 1966, 1972, 1974 (STS), 1986, 1989, 1993, 1995, 1996, 2001, 2003, 2005, 2006, 2007, 2010, 2012, and 2013.

Note: Storm #1 of 1982 (H Alberto) was a H that delivered TS-force conditions to the Lower Fl. Keys of the U.S.

ALL U.S. HURRICANE LANDFALLS:

3 = 1886

2 = N/A.

1 = 1851, 1854, 1867, 1888, 1906, 1909, 1913, 1921, 1929, 1934, 1936, 1945, 1957 (MH), 1966, 1972, and 1986.

This is a visible satellite image of H Bonnie from June 26, 1986-as it makes landfall in SE TX. It remains the most recent TC of H intensity to strike the U.S. coastline during the month of June.

ALL U.S. MAJOR HURRICANE LANDFALLS:

1 = 1957.

This is a historic radar image of category four H Audrey (near peak intensity) as it bore down on the upper TX and SW La. coastlines of the U.S., on the morning of June 27, 1957. It remains the most intense June TC to ever develop in the Atlantic basin during the month of June, as well as the most intense June TC to strike the U.S. shoreline.

INTERESTING FACTS:

1) All Atlantic Basin Tropical Storms:

a) There were a total of 88 TS or STS systems that developed in the Atlantic basin during the 163 year period of 1851-2013. This equates to a statistical mean of one TC of STS or TS intensity developing during the month of June every 1.85 years.

In addition: Storm #1 of 2008 (TS Arthur) was a May TS that maintained TS intensity into the month of June.

b There were a total of 33 June TC's that achieved hurricane (H) intensity during the aforementioned 163 year period. That equates to one June H every 4.94 years on average.

c) There were a total of 2 June TC's that ultimately achieved "major" hurricane intensity at some point during the month of June. These figures would constitute a statistical mean of one June major H traversing some portion of the Atlantic Basin every 81.5 years.

d) Hurricane Audrey holds the record as the most intense H to ever develop during the month of June. It intensified into a category four hurricane at 8 am CDT on June 27, 1957-just before it struck the U.S. coastline near the TX/La. border. At the time, it had a MSW of 145 mph and a corresponding barometric pressure of 945 mb. Moreover, it also holds the record as the most recent "major" hurricane to strike the U.S. coastline during the month of June.

e) There were 2 TCs of at least TS intensity that developed during the 2013 season, and are the most recent tropical storms to form during the month of June. They were TS Andrea and TS Barry, respectively.

f) Hurricane Chris of June 2012 is the most recent June TC to become a hurricane during the month of June.

g) The three longest periods of consecutive years without a TC developing anywhere in the Atlantic Basin during the month of June are 1874-1880, 1914-1921, and 1947-1954. In addition, 93 out of the 163 hurricane seasons (57.1%) in the historical record, didn't have a TS form during the entire month of June.

h) The 1886, 1909, 1936, and 1968 Atlantic Basin hurricane seasons are shown to have been the most prolific for "June" TC formations-with 3 each, respectively.

i) The 1886 Atlantic basin hurricane season holds the record for spawning the most hurricanes-during the month of June-with 3.

j) The 1957 and 1966 Atlantic Basin hurricane seasons each spawned 1 MH during their respective seasons.

2) All U.S. Tropical Storm Landfalls:

a) There were 64 June TS or STS systems that made a U.S. landfall (or strike) during the aforementioned 163 year period. This equates to one June TS landfall per 2.55 years. Astonishingly, a full 72.7% of all Atlantic basin storms made landfall in the U.S. This is a reflection of the primary breeding grounds being located in such close proximity to the U.S. coastline.

b There were 19 hurricanes that made a direct strike on the U.S. coastline during the month of June. This equates to one land falling June hurricane every 8.58 years. Furthermore, a full 57.6% of all Atlantic basin hurricanes struck the U.S. coastline.

c) Hurricane Audrey of the 1957 H season is the only known TC to have made a U.S. landfall, at "major" hurricane intensity, during the month of June.

d) Aside from H Audrey coming ashore at "major" hurricane intensity, there are a total of seven different hurricanes currently listed in HURDAT as making a U.S. landfall at category two intensity or greater. They are category four hurricane Audrey of 1957 (145/945), 3 different category two hurricanes that made landfall in 1886 at the same exact intensity (100/973), category two Texas hurricane of 1909 (100/972), category two Louisiana hurricane of 1934 (100/966), and category two hurricane Alma of 1966 (100/982). This would equate to a category two or greater landfall every 23.29 years. It is also important to note that the HRD preliminary reanalysis suggests "Audrey" came ashore as only a 120 mph category three storm. Regardless, this designation would still keep it as a "major" hurricane landfall on U.S. shores.

e) Hurricane Bonnie is the most recent June hurricane to have made a landfall on the U.S. shoreline. It made landfall between Sea Rim Park and High Island, TX. at 5 am CDT on June 26, 1986, as an 85 mph/990 mb category one hurricane. Based on the historical record, the U.S. is well overdue for another June hurricane strike. In fact, this current hurricane drought (of 28 years) constitutes the longest known interval the U.S. has encountered in the entire historical record.

f) The most recent "June" TS to make a direct U.S. landfall was TS Andrea of 2013.

g) The longest periods of consecutive years without a landfalling U.S. TS (during the month of June) include 1855-1865, 1874-1880, 1881-1886, 1914-1921, 1947-1953, and 1975-1982. In addition, 109 out of the 163 H seasons (66.9%) didn't have a U.S. TS strike.

h) The 1886 H season had the most land falling Tropical storms-for the month of June-with 3.

i) The 1886 Atlantic basin hurricane season also leads the way for U.S. hurricane landfalls-during the month of June-with 3.

j) The 1957 H season contained the only known U.S. landfalling hurricane that came ashore at MH intensity.

FUTURE BLOG ENTRIES THREADS:

I will post additional updated blog entries threads (similar to this one) for the other respective months of a calendar year. With that in mind, the next entry should be a thorough examination of the entire climatological record for "July" TCs in the North Atlantic basin.

As always, thank you so much for taking the time to read and/or post in my blogs threads. I hope you have a great rest of the weekend!

Most sincerely,

Tony

Possible historical occurrence in 2014?:

If the North Atlantic basin can spawn a TC of at least tropical storm intensity, it will tie the record for the most consecutive seasons with at least one TS forming during the month of June. Currently, the five-year span of 1956-1960 holds the record, exclusively.

Revision to initial post:

I just corrected a typo that was noticed by another member (thanks to Roger Smith), where I had inadvertently stated TS Arthur was a May TC that lasted into "July."

[ncforecaster89]

Another fascinating historical note:

The U.S. is currently enduring the longest period (28 years) without a "June" landfalling hurricane in the entire historical record (1851-present). The preceding longest period without a "June" hurricane strike, on the U.S. coastline, was 18 years (1888-1906).

Thanks to Roger Smith for suggesting I list this interesting fact.

Glad to be a tiny bit of help, I guess July won't be a lot more work than this, but Aug-Sep-Oct will be formidable.

 

Anyhow, here's another statistical summary that tracks the changes over time in the number of storms. I chose the rather simple method of counting all named (TS intensity or greater) storms in consecutive 10-year intervals starting with 1860 when one first became available.

 

This is what I found, hope I counted right.

* add one to 2008 and all subsequent years to get named storms active in June (Arthur from May 2008) .. (means for that adjustment are in brackets)

If the North Atlantic basin can spawn a TC of at least tropical storm intensity, it will tie the record for the most consecutive seasons with at least one TS forming during the month of June. Currently, the five-year span of 1956-1960 holds the record, exclusively.

Watching closely to see if the low, situated just inland of the SC coastline, will develop into a TC of TS intensity. If so, it will tie the aforementioned record for consecutive seasons with at least one "June" TC formation.

I will be posting a thread, in the next few days, detailing "July" TC formations for the period of 1851-2013.

Hey Roger, thanks so much for providing the excellent chart listed in the preceding comment. Very well done!

Dates for a few hurricanes were missing above:

 

6-27-1957 (cat-4 H Audrey) sw LA

6 -9-1969 (cat-2 H Alma) FL

*6-19-1972 (cat-1 H Agnes) FL, second landfall not shown in table, 6-22 NY/CT

 

(note: the 7-1-2010 TS would be in the July chronology)

 

ANALYSIS: There is a somewhat counter-intuitive lull around the summer solstice, perhaps some sort of transition from spring to summer circulations temporarily dampens the production of storms. The peak of storm landfalls around 26th is not really matched again in July although some days near the end of July have five events. See the July thread for the continuation of this table.
